Crimea - America has no business there

We all have been hearing on the news (a little less now the main wave has subsided) about Russian and Ukraine interactions over Crimea. This event has received a lot of coverage from all sides, with Russia and Ukraine seeking to solve the issue independently, the Ukrainian foreign minister requesting the withdrawal of foreign interferes. Why does America think it has a right to make threats and sanctions against Russia? Russia is coming to the defense of a densely populated Russian area, and not using military force or shedding blood. If anything Russia is being the more reasonable of the parties. On the other hand, America is being hypocritical and whining. Let's not forget the countless countries America "inducted" into its great empire. Hawaii, Guam, the Philippines. Areas which had NO American citizens or influence. Russia isn't half as drastic as that, simply giving comfort and order to Russian citizens in Crimea, evidenced by the huge reception held by citizens upon the arrival of Russian forces. While it can't be said that what Russia is doing is holy, or not crossing some lines, because it certainly is. But what we should be considering is that, is it really America's place to tell people how to live their lives, with the current imperialistic track record it has.
