Part of the reason that Russia has acted to annex Crimea and will likely grab at least the eastern portion of the Ukraine in the very near future is that every American president since the break-up of the Soviet Union has loudly, and at times obnoxiously, proclaimed that the United States is the only remaining superpower in the world ("Putin's land grab," March 19).
Mr. Putin's actions are his way of saying that Russia also a superpower, and since he has ground troops and nuclear weapons to back up his claim, he makes a pretty convincing albeit heavy handed case.
The bottom line is despite our government's outrage, the U.S. has no more business intervening in this crisis than Russia would have in trying to influence a dispute between the United States and Mexico. I say this as a son of a woman and grandson of four people who were born in the Ukraine.
Like it or not, all great powers have their own spheres of influence. They also have limits to the actions they can take when another superpower acts.
