Is the united states a walking joke?

I do not see how a country that mixes religion and state( use the excuse to mix it that it is not barred), invades more countries than Nazi Germany, kills a bunch of innocent people during world war 2 in the bombing of japan(let alone i do not see why they glorify it in movies like pearl harbor), kills one million innocent Iraqi lives, prevents social equality, makes weapons of m destruction, gets labeled the leader of the free world. Shouldn't be Russia or Canada , at least they believe in the separation of religion and state
