Unocal is not a major source of oil for the US. Most of it's production goes to Thailand, Korea and Japan. And still would have even if CNOOC bought it.
Maybe true; maybe not...when push comes to shove and there is truly a shortage. Or a war.
The Chinese govenment/military should not be given command and control of the routing of such a huge amount of oil.
We shouldn't ever have allowed panama to use China to manage the canal either. Won't ever deny the U.S. use to ti. Will just destroy the locks in the event of a war/conflict with the U.S.
