So 'the entire Western world' condemns Russia for moving troops into the Crimean peninsula of Ukraine where a big strategic Russian naval base is located, and Russian-supporting, Russian-speaking people are in the majority - and thinking about doing the same in the east if the country where there is a very large Russian/Ukrainian trade and the main industrial base of the nation using Russian fuel.
I can see that the USA has no experience of being an 'ex-empire', but they do have military bases in other Lands. So I wonder what the USA would do if it had a large naval base in the Crimea for instance, and it was full of US-supporting, English-speaking people? I would guess they would have warships in the water and troops at airports (at least)?
Basically the West's politicians are saying to Russia, 'OK you have allies in a neighbouring country that is in political turmoil with one part do the country trying to split from you, and other parts where you have huge public support and strong trade links and a military base -but we want you to do nothing'
Surely Obama knows in his bones he would be acting EXACTLY like Putin in the same circumstances?!
