King Hussein was facing an attempt by Palestinian militants to seize control of Jordan. There was a civil war going on. The other side was aided by a Syrian military invasion in the north of the country. I supported the king then and would support him now.
Bashar Assad may be qualitatively different from the old man in Syria. Hafez was an intensely practical (or cynical) man. He had no philosophical opposition to the US. When US presidents were willing to deal with him--as Nixon and the elder Bush were--he was willing to deal with them. Bashar on the other hand actually seems to support outfits like Hezbollah, and not just for the reasons his father would do so--reasons of expanding Syrian power into Lebanon.
