"All this saber-rattling is despicable. Neither Russia nor Iran threaten the U.S. and there is no reason why the U.S. should be eager to defend Taiwan or Ukraine (and also Israel). China’s military budget is miniscule compared to the U.S. and the only real threat it represents is as a competitor on world markets, where it is already dominant in a number of key sectors. The U.S. has to get off this global dominance militarism wagon but how do we do it when both major parties embrace it?"
