I strongly disagree. It is just that US weapons have been grossly useless and it has been proven many times. For example when Yemenese attacked these Arabs none of the defenses that US had sold them worked. You are saying that the Arabs don't know how to use them but what about when the same people attacked US bases in Saudi Arabia and the same weapons operated by US military personnel protecting US military personnel also didn't work at all?
Today I was watching a documentary how US has toppled 100 governments in the world and how for their benefits they have changed and destroyed the countries.
Russia maybe wrong in attacking Ukraine. But Russia cannot be defeated. Europe has to go back to Russia for the oil and gas - for sure.
