I think you're the one applying anti-vax logic here. Imagine beating a guy up for looking at you wrong and then get into a semantic argument with the judge on how you shouldn't be charged with assault because it was actually an act of defense, you see if you hadn't assaulted them they would surely have assaulted you so it's defense.

You're basically saying the US don't need a Department of Defense because the Department of War is doing such a good job.

Yeah, otherwise the USA would have been invaded by Cuba, Iraq, Vietnam, Syria, Afghanistan, Yemen and a hundred more, and they all would have a fight over who can have it. Thank god the US defended themselves against those terrible guys. Especially the WMDs were quite the close call, the Iraqis were minutes away from nuking the land of the mart.

>We haven’t been invaded because our military maintains a strong deterrence and strategic depth.

How do you know that's the reason? There are many countries with very low defense spending that haven't been invaded since WW2.
