If the US could invade Iraq without UN support and under the pretense of the moral high ground as defined by the US, then so can Russia invade Crimea. If the Kosovo can leave Serbia and become it's own country under the support of the US even though it is historically Serbian but by population Albanian so can Crimea which has a Russian majority. The US has made their bed and now it is sleeping in it. Precedence is a bitch, the US set the precedent and now they are winging about what is happening in Crimea !! Russia supplies 60% of Europe's energy and it will increase to 80% ... the US has nothing to stand on. If they apply sanctions, the Russians will increase the price of gas and oil and have Europe pay for them just for giggles.
