“If...you mean spending our money and sending our good people...I am an isolationist...The leader of the Ukraine is as much of a thug as Putin is.”
So the bottom line is, Americans are too good to bother with anyone else? Apparently, being moral means more to you than being effective.
That combination of prissiness and condescension is calculated to bring us more of the same: timidity among unaligned nations, and skittishness on the part of erstwhile allies - nations with more at stake than we’ve got, who will look at our long history of inconstancy, and dismiss our endless moralizing as so much talk.
Mind you, they’re not going to be dazzled by our glittering moralistic example, and fall in line spontaneously.
Effective? You mean like all the botched operations and wars in the past 60 years or more? The US has no obligation to send our sons and daughters to fight for other countries, none.
