A friend e-mailed over the weekend:

The New York Times reports today [Saturday] that President Obama learned of Iran’s secret facility in December 2008 — before he became president — and that the facility’s purpose as a covert enrichment plant became unmistakably clear to our intelligence services during the early part of this year.
Based on the information we had even before this, any reasonable person would have understood that Iran’s nuclear program is intended to provide it with military capabilities. If this latest information is correct, there can no longer be any pretense of an argument to the contrary.
What has President Obama done since he has known about the secret enrichment plant? Given his Nowruz message; apologized for U.S. involvement in the overthrow of Mossadeq in the 1950s (!); offered a late and weak rhetorical defense of the Iranian protesters as they tried to shake the regime that oppresses them; and accepted Iran’s absurd offer to negotiate on, among other things, nuclear disarmament (“nuclear disarmament,” in international lingo, normally means that the United States must disarm); given deadlines that keep slipping.
Here is what he has not done: explained the threat and what the United States must do to address it; pursued any significant additional sanctions, unilateral or multilateral.
President Obama’s “engagement” approach to Iran appears to have been, and still be, based on an assessment of what he thinks the solution to this problem ought to be, rather than on what will actually be required to solve it successfully and peacefully. If he has anything like an actual strategy for how he will get the Iranians to stop their nuclear program, it is not apparent.
When President Kennedy was informed of nuclear missiles in Cuba, he took prompt action that was well-explained, and resolved the issue peacefully. If he hadn’t, there would still be nuclear missiles in Cuba.
Note also that in yesterday’s Obama-Sarkozy-Brown press conference, President Obama’s remarks were the vaguest and most globalist of the three, mentioning nuclear disarmament and rights to peaceful nuclear energy. He made Gordon Brown (“line in the sand”; “we will not let this matter rest”) sound like George Patton, or at least George H.W. Bush.
