If the alert is because they expect the wackos to pattern an attack after the US COLE, perhaps the tankers sitting in US harbors need to be watched and armed.
I don't know what our intelligence agencies are doing, but whatever it is, they don't seem confident that they are going to stop another attack. Given this, I believe it is unconscionable for our political leaders to refuse to take the one step that would most hinder the terrorists in attacking us again. And that is first, to seek out and deport all people here illegally from terrorist states (the states that have been referred to by political leaders)and second to deal with those people here on visas from these states. I believe the risk merits revoking all these visas immediately but failing that, at the very least all these people should be required to renew their visas immediately at which time they will be investigated (and I mean real investigations), fingerprinted, and photographed. Any adherents of radical islamic fundamentalism or those who harbor the slightese anti-American views should be deported. Those people who do not comply should be located and deported on the spot.
Congress and political elites have imposed on America over the past 30 years an immigration policy that has never been supported by a majority of Americans and this policy is literally killing us. Now they are failing to do the one thing that would be most effective in protecting us.
