Why the f*ck would the United States guarantee Ukraine's security?
That's a very good question, and it seems to be a major point of contention between the US and Europe/Ukraine.
American guarantee of Ukraine is about as big as that of an African-American boy born in the inner city, to become CEO of Apple Inc
Well, that Afro- Am has the opportunity to become CEO of Apple, it's question of the effect of his environment. Whereas, an American guarantee is a question of strategic interest.
It seems Trump wants to have closer ties with Russia. He wants to go back to the age-old strategy of keeping Russia closer to us than they are to China.
Which is another point of difference between us and Europe. We see China as much more an adversary to us than Russia, Europe sees Russia as its main adversary (or so it seems).
If I understand correctly
Trump said European. Maybe I misread, but non-European foreign troops makes no sense.
