Obama sure has lots to answer for
"U.S. military forces have been at war for all eight years of Obama’s tenure, the first two-term president with that distinction. He launched airstrikes or military raids in at least seven countries: Afghanistan, Iraq, Syria, Libya, Yemen, Somalia and Pakistan."
Despite my meagre knowledge of U.S. war involvement I can spot a couple that probably deserved it. They are mostly all troubled areas, so is it really fair to blame Obama?
