f*ck yeah USA is the greatest threat on earth, they spend 45% of the total global defense budget and built bases around the world, promote "peace and freedom" (what a fcking joke ), invade countries on the basis of fabricated evidence ( Iraq had WMD, thats what CIA says). China's current spending is too little, it should atleast be close to or higher than the US spending because China is located in a really bad neighbourhood, to name a few, india, s.korea, philipines, vietnam, taiwan, russia, and last but not least japan.
