No... just for national / geopolitical interests. I'd argue that Major Hasan shared those with terrorist groups, and actively conspired as a solider against us. Not crazy. Far different from the recent shooter.
Still crazy. People who decide to attack innocent people due to their crackpot beliefs are not mental stable. Also, it is my understand Hasan was committing jihad. He had correspondence asking whether killing innocents was acceptable and when jihad was appropriate. A person who kills the leader of a country they don't agree with isn't crazy (at least, not much); a person who kills random, innocent people because they don't agree with the country's (whom, the people killed have no control over) politics is.
