Amateurs do tactics, experts do logistics, as we learn in the military.

When there's no light at the end of the tunnel, it's hard to keep things going.

One answer to transportation infrastructure funding is public-private partnerships.

Our 21st-century world is an incredibly dangerous one. Between brutal civil wars, violent extremism, spreading autocracy, rising inequality, territorial expansionism, election interference, and nuclear proliferation, our policymakers have their hands full.

The Democratic Party has been perceived to have a deficit of credibility on defense issues since the Vietnam War, unfairly or not.

During my years in the Navy and in the White House, I was involved in assessing how a war with Iran would go. In summary: It would be ugly.

When all Americans believe that the people we elect deserve to be in power, that their conduct in office is worthy of respect, and that they can be held accountable for their decisions, our politics will finally be worthy of our great people.

In the Navy, I slept mere feet from a nuclear reactor, so I have no knee-jerk opposition to traditional reactors.

In the military, we just don't leave fights.

At the end of the day, Israel is its own self-determining government.

For a public option, I voted for that when I was in Congress, and the Senate couldn't stand up to the health insurance industry and took it out.

Look, it's no longer about capacity, how many ships, how many air wings, how many battalions. It's about capability. If we dominate cyber space and know and can read the other guy's mail, and with a very accurate laser-guided munitions put it in this window or that window, it's not how much, it's knowing exactly where to pinpoint a target.

I don't look at Israel through the prism of running an election.

For far too long we have continued to mark our military prowess by the size of our forces: believing that numbers of ships, planes, and brigades is what most matters - just like during the Cold War.

I'm a guy that verifies before he trusts.

I believe we should be investing in the potential of nuclear technology based on thorium, to end the use of plutonium and lead to much safer nuclear power plants, less toxic nuclear waste, and less opportunities for nuclear weapons proliferation.

The citizens of this nation gave us - my wife and I - a health care plan that saved our daughter's life.

Trump is not the problem. He is the symptom of the problem where Americans no longer believe that the system works for them.

Executive privilege is nowhere to be found in the Constitution, and thus is a very limited principle.

We did more to thwart Iran's nuclear ambitions with a computer virus than we ever could have with bombs (and we did still more with diplomacy - the abandonment of which is also bad for our military, because militaries can only stop a problem, not fix a problem).

The way forward in the Middle East, as it has been around the world and throughout history, is communication. There must be direct talks between the Israelis and Palestinians, mediated by the United States.

The United States must ensure that Iran does not attain nuclear weapons, as this poses a direct threat to our interests, including Israel, and would in all likelihood provoke a regional arms race.

Everybody in the military is a Democrat. They just don't know it.

You can get so focused on a strategy and making it work that you lose sight of your larger mission.

Before the CFPB, there was no single agency or entity within the federal government tasked with protecting Americans from predatory or negligent practices of banks, credit card companies, mortgage lenders, payday lenders, credit rating agencies and other financial service businesses.

Well, you know, I kind of lived my whole life with people, on a Navy ship, and I'm son of an immigrant. And we've all - really appreciate being able to make something clear in a simple way that families quite understand.

I want to be a public servant, not a politician.

Cyberspace is the new domain of warfare.

Launching a ground war against Iran would require hundreds of thousands of troops for a 'regime change followed by nation-building' operation, as we attempted in Iraq. Iran has a much more modern military, more than double Iraq's population, and almost four times the landmass.

I want to restore U.S. leadership within a rules-based liberal world order that collectively holds nations accountable for their illiberal behavior, whether in foreign or domestic spheres.

Nobody under 40 carries a comb.

The greatest brotherhood, sisterhood that I was ever a part of are veterans.

Some of the greatest national security threats we face cannot be defeated or defended by traditional military hardware, but only by greatly enhanced cyberspace warfare, including both offensive cyber-warfare and cyber-security.

We need a president who will stand up for the CFPB and get it back into fighting shape. It is too important to be allowed to disintegrate.

The Iran deal was working. As a solution to the problem of Iran developing nuclear weapons, it was actually working quite well.

Just as we need a productive warrior force to carry out our national defense mission, our national workforce must be equally able to carry out our economic mission.

What this nation most wants, most yearns for, most needs is someone where people know, all Americans know, that even when they disagree well with him, he will always be accountable to them above one's party, above self and any special interest.

We only won our freedom because of our allies, and we can only sustain it because of them.

I wore the cloth of the nation for over 31 years in peace and war, from the Vietnam and Cold War eras, to Afghanistan and Iraq, and the emergence of China.

We must make sure the stigma is removed around mental health and commanders must make it clear on a consistent basis that their door is open for everyone. Servicemembers need to know that command is there for them, to offer assistance however and wherever needed.

Americans want someone who is accountable to them above self, above party, and above any special interest. They want a President that has a depth of global experience to restore U.S. leadership to the world and to protect our American dream at home.

Nuclear power can continue to help us reduce our greenhouse gas emissions, but we must do everything we can to make it safer.

Torture is and must remain illegal. Warrantless wiretapping is also illegal, as was the transfer of Guantanamo detainees to Qatar without proper notice.

I want to be that President who serves the American people the way they deserve to be served.

I have seen how payday lenders and check cashing outfits set up in towns around military bases to take advantage of young service members, whose starting salaries are barely over $20,000 per year.

If you have a president who is really trusted, then you can move and advance those policies that actually make the American dream available to everyone.

I do not agree with the use of 'signing statements' to effectively act as a line-item veto, except when the President believes a law or a provision within a law is unconstitutional.In general, if a President signs a law, they are committing themselves to enforcing it. If they don't believe it should become a law, they should veto it.

We need to restore U.S. leadership to a world order that is rules-based in order to protect our American dream here at home.

In the face of a rising China, along with authoritarian regimes from Brazil to the Philippines to Turkey to Russia, and the constant presence of belligerent non-state actors, we need to reform our military to deal with asymmetrical threats.

Created by Congress as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the CFPB was a direct response to the financial crisis and ensuing Great Recession that began with the subprime mortgage debacle and the unraveling of Lehman Brothers investment bank.
