'Modern Warfare,' 'Black Ops,' these are all the next level of video games. The people are more detailed, the fighting is more exact, and I can't speak for every gamer out there, but I know when I play, I feel like I'm actually in the game. It's that intense.

There is such a thing as legitimate warfare: war has its laws; there are things which may fairly be done, and things which may not be done.

Modern warfare is increasingly expeditionary and requires platforms with extended range, flexibility and endurance.

We plan to eliminate the state of Israel and establish a purely Palestinian state. We will make life unbearable for Jews by psychological warfare and population explosion. We Palestinians will take over everything, including all of Jerusalem.

Love is a kind of warfare.

While the nature of warfare is changing and wars are moving into cities, they are also becoming longer and their consequences more impactful.

New technologies are rapidly giving rise to unprecedented methods of warfare. Innovations that yesterday were science fiction could cause catastrophe tomorrow, including nanotechnologies, combat robots, and laser weapons.

We must not forget that chemical warfare will sooner or later bring in its wake bacteriological warfare, pest propagation, typhus and other serious diseases.

What makes you a SEAL, what makes you a SEAL is being a good tactician on the battle field, understanding how to shoot, move, and communicate, knowing small unit maneuver warfare. That's what makes a good SEAL, and so that is the course of instruction that I taught, was getting SEAL platoons ready for deployments to Iraq and Afghanistan.

When you have warfare, things happen; people suffer; the noncombatants suffer as well as the combatants. And so it happens in civil war.

If there is anything worse than international warfare, is civil warfare, and the United States was destined to experience it in the extreme of bitterness.

The Spanish Empire eventually collapsed because of its expensive taste for warfare and conquest.

If you look at human society, it is very easy, of course, to compare our warfare and territoriality with the chimpanzee. But that's only one side of what we do. We also trade, we intermarry, we allow each other to travel through our territory. There's an enormous amount of cooperation.

The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.'

I know now that gang warfare is not the Middle East or Northern Ireland. There is violence in gang violence, but there is no conflict. It is not 'about something.' It is the language of the despondent and traumatized.

I have said that propaganda, misinformation, and disinformation have always been part of political warfare. Social media and other new platforms have given it a new life and reach through which the fake news phenomenon can reach everywhere.

Bonobo studies started in the '70s and came to fruition in the '80s. Then in the '90s, all of a sudden, boom, they ended because of the warfare in the Congo. It was really bad for the bonobo and ironic that people with their warfare were preventing us from studying the hippies of the primate world.

If you look at footage of the Newfoundland Regiment, you see they are at rest and giddy and being silly with one another. Silliness is the antidote to trench warfare.

Raising kids is part joy and part guerrilla warfare.

Logistics is the ball and chain of armored warfare.
