I understand it's nauseating to Trump supporters. But if you look at it from his point of view, his country is getting bombed to smithereens everyday. Death and mayhem everywhere. If it weren't for US weapons the war would have long been over. He is grateful for whatever support he is getting and yes, he may have gone a little overboard with the praise but it's better for him to err on the side of flattery than to risk appearing not being grateful enough.
