President Barack Obama is right to refrain from action against Russia ("The Obama doctrine under fire," July 25). After years of war, the U.S. has learned its lesson: don't mess with a hornet's nest thousands of miles away.
Putting boots on the ground in Ukraine would be dangerous. Such action would escalate tensions between Russia and the West. More importantly, this could embolden Ukraine to snatch the ethnically Russian Crimea from Russian President Vladimir Putin's hands.
If Ukraine and Russia go to war over Crimea while American troops are stationed in Ukraine, the U.S. would almost certainly become embroiled in another war. And this time, the U.S. wouldn't be fighting untrained terrorists with limited technology. Uncle Sam would have to wrestle the well-trained, technologically advanced Russian Bear.
Russia has yet to directly harm the United States. Until it does, President Obama is right to avoid the possibility of a costly war.
