Excellent article in the American Thinker that many here may dismiss on the basis of its origin. But to do so is to dismiss the reality that the argument asserted (considered specious by the Left) is very real and palatable to Israelis living under the threat of extinction by rogue Iranian state, unreliable allies, and a hand-wringing, self-absorbed Socialist Europe. A few excerpts below.
The Holocaust weighs heavily on Israel and its leaders. Everyone knows the story of Jewish organizations pleading for help but helpless before the indifference of those in a position to make a difference. This history discourages looking at the world through rose-colored glasses. American liberals blithely dismiss the Iran threat because they assume that Iran is rational, that it will never attack Israel with nuclear weapons because of the threat of retaliation. Israelis are not inclined to put their faith in this convenient theory that validates inaction. Obama says that he has Israel's back. But what if, when things get difficult, he doesn't have Israel's back? Countries have interests, not friends.
The Israelis have the capacity to mount a substantial attack. Exactly how effective this would be depends on factors hidden by the fog of war. Currently the U.S. has two carrier task forces in or near the Persian Gulf. If the Israelis attack, the U.S. will certainly have at least an hour's advance notice, if not much more. Our radar planes will see the Israeli's coming. If the Israelis attack, the Iranians have threatened to close the Straits. Although they cannot win a navel war in the Gulf, they certainly have the capacity to cause a lot of trouble. It would seem not to be in the Iranians' interest to close the Straits, but they may just decide to roll the dice and do it. We just don't know and can't make a confident prediction. If we sit back and let the Iranians take the initiative, we will be in a much worse position than if we blast the Iranian assets before they can take action.
The Iranians may see it to be to their advantage to close the Strait. If remotely controllable mines were used, the Iranians might be in a position to open and close the Strait as they desired. They could blackmail the West by offering to let tankers through in exchange for concessions. This probably wouldn't work and would lead to increased military pressure on Iran, but the Iranians, having been treated to a weak Western response to their nuclear bomb program, might underestimate the U.S. and other countries.
