I do not care for Mr Trump's rhetorical style. I prefer TR's "walk softly and carry a big stick." I see a bit too much trash talk, and a bit too much "reality TV" to be happy with style.
The fact is, yeah, if a can of whoopass is to be opened, it's rather bad to be on the wrong side of it.
Without Russian and Chinese support, however, since we live in a multi power, multi polar world, there are some side effects to whoopass cans being opened that I hope Mr Trump is aware of.
