It is getting worse because the U.S. is helping it along by ignoring the U.N.
We could strengthen it by allowing the UN inspectors to do their work. Russia and China need to be heeded for their sensible approach in not going in trigger happy.
Also, it could easily be spread over the Middle East. I wouldn't say it's worse than Iraq
which has been utterly destroyed as a country. It's a different kind of destruction, in Iraq, it's slower acting and has assumed deterioration over time.

Another way to strengthen the UN would be to send in U.S. ambassadors who would
be participants without trying to superimpose U.S. policy and muscle the UN into
accepting a hegemonic foreign policy.

Also, a Palestinian state would help as well.
