The great and abiding lesson of American history, particularly the Cold War, is that the engine of capitalism - the individual - is mightier than any collective.
So if we announce we're going to have a no-fly zone, and others have said this. Hillary Clinton is also for it. It is a recipe for disaster. It's a recipe for World War III. We need to confront Russia from a position of strength, but we don't need to confront Russia from a point of recklessness that would lead to war.
In battle, combatants engaged in war against America get no due process and may lawfully be killed. But citizens not in a battlefield - however despicable - are guaranteed a trial by our Constitution. No one argues that Americans who commit treason shouldn't be punished. The maximum penalty for treason is death. But the Constitution specifies the process necessary to convict.
You can be strong without being involved in every single civil war around the world.
The main thing I say on war is that we need to obey the law and formally declare war.
The coarsening of our culture towards violent death has more consequences than war. Tragically, this same culture has led to the death of 50 million unborn children in the last 40 years. I don't think a civilization can long endure that does not have respect for all human life, born and not yet born. I believe there will come a time when we are all judged on whether or not we took a stand in defense of all life from the moment of conception until our last natural breath.
John McCain's complaint is we're either not at war somewhere, or if we're at war, we leave too soon. So we're not there soon enough, and he wants us to stay forever wherever we send troops.
Secretary [John] Kerry has called Civil War [in Syria] an unbelievably small war that we're going to get involved with.
You have to decide in advance whether you're ready go to war. If you guys are ready to send a million troops into Ukraine and fight World War III, you're going to do it without my support because I think that's a really foolish notion.
We need to get insurance out of the way and let the consumer interact with their doctor the way they did basically before World War II.
This whole sort of 'war on women' sort of thing, I'm scratching my head because if there was a war on women, I think they won.
I would have voted 'no' on the Iraq war and 'yes' to Afghanistan.
I think this sets a very bad precedent, the president unilaterally on his own starting war without any consent from Congress.
I do not yet know if I will find a Romney presidency more acceptable on foreign policy. But I do know that I must oppose the most recent statements made by Mitt Romney in which he says he, as president, could take us to war unilaterally with Iran, without any approval from Congress.
I tell people I won't vote to go to war unless I'm ready to go or send my kids.
I think that, most importantly, when I see issues of war, I see them in a personal vein, and I am reluctant to go to war unless there's a real, valid American interest because I've seen the wounded soldiers.
We should understand the limitations of war. We should understand the sacrifices our young men and women go through losing lives and limbs. And they should only do it for the highest of purposes.
I just can't vote to go to war unless I think there's a real clear-cut American purpose in the war, that we're going to win and that we're not going fight for stalemate.
I don't think he fully analyzes the situation. If you destabilize [Bashar] Assad and punish Assad, you do embolden terrorists. You embolden al-Qaida because al-Qaida is on the other side of this war. So, one side wins if you destabilize the other side. So, he will be emboldening al-Qaida and the Islamic rebels. And I'm not so sure they're better than Assad.
I think there's evil on both sides [of Syria], and I think that's one reason I don't want to be involved in civil war. I see things in personal terms. I just can't see sending one of my sons - or your son or daughter - to fight in a civil war, where on one side we have a dictator, who in all likelihood gassed his people.
I want to collect more records from terrorists, but less records from innocent Americans. The Fourth Amendment was what we fought the Revolution over! John Adams said it was the spark that led to our war for independence, and I'm proud of standing for the Bill of Rights, and I will continue to stand for the Bill of Rights.
I think when we think about the judgment of someone who might want World War III, we might think about someone who might shut down a bridge because they don't like their friends.
I think that if you believe in regime change, you're mistaken. In 2013, we put 600 tons of weapons - us, Saudi Arabia, and Qatar - into the war against [Bashar] Assad. By pushing Assad back, we did create a safe space.
There is often variations of evil on both sides of the war. What we have to decide is whether or not regime change is a good idea. It's what the neoconservatives have wanted. It's what the vast majority of those on the stage want.
I think that there is a bipartisan consensus that's incorrect that we should have the whole world be in NATO. For example, if we had Ukraine and Georgia in NATO - and this is something McCain and the other neocons have advocated for - we would be at war now because Russia has invaded both of them.
