Recent news that the Israelis believe Iran is perhaps 3 years from an atomic weapon, based on recent difficulties, is at some level comforting--if true (and assuming Iran doesn't buy a warhead or six to bridge the gap).
But don't forget that Iran doesn't need atomic weapons to act like an enemy despite our own nuclear arsenal. Iran under the mullahs is a threat right now.
Iran fights us in Iraq.
And Iran fights us in Afghanistan.
None of this is new news, of course. Iran has helped our enemies in Iraq and Afghanistan for a long time. But perhaps our media will be more willing to report on this since it can't be explained as a Bush (or more likely, Cheney) plot to start a war with Iran.
Imagine what Iran will do when they have the shield of nuclear weapons--assuming they don't have plans to use them for goals that seem irrational to us?
And remember that our problem with Iran isn't whatever weapon they have or do not have. The problem is the regime that has been waging war on us relentlessly ever since the mullahs came to power. Pray that nuclear weapons don't become another weapon to use in that war.
