The Grenada mission was necessary to rescue American college students who were trapped in Grenada due to the civil war in that country.
Once again, I refer all of you to the War Powers Act of 1973.
I will also remind all of you that G.W. Bush's reason for liberating Iraq was to enforce the 17 U.N. resolutions that Hussein (Saddam, not Barack) had continually violated since the 1991 Gulf War cease fire agreement.
I have no problem with Obama doing what he is doing, but it's pretty obvious that he has no clue how to be a true "commander-in-chief". He's a friggin' Chicago machine politician, not a warrior, not a military strategist, and certainly not a leader. He is a follower and a delegator.
The best Presidents are the ones that outline a military objective, then allow the military to do their jobs, without micro-managing every move the military wants to make.
Obama should stick with working on his jumpshot, and let the military do their jobs.
