1ºFaku Ndamase we have conventional/ nuclear missile fields on 4 continents and the worlds largest forward deployed nuclear armed air force and navy in the world.
At all times atleast 10 nuclear armed B-1, B-2, B-52s airborne in international air space orbiting prepared to deliver long range air launched nuclear warheads in addition to our surface warships and submarines which both quality and quantity out does both Russia and China combined.
By the way, I've been everywhere from Iraq to Ukraine, and all the way to the Mariana Islands and outward near the Scarborough Shoals and Spratly Islands the past 15 years. I do know a thing or 20 as to why Russia refused to attack us despite aiding Ukraine,
And why China didn't do crap over Taiwan a few weeks ago. They know a lot better than you do they stand no chance. Literally they'd have to destroy the entire world along with themselves in the first volley just to ensure we didn't guarantee their destruction aswell.
