US President Barack Obama underestimates the threat Iran poses to global security. Were this not the case, he would not have sent CIA Director Leon Panetta to Israel ahead of Prime Minister Binyamin Netanyahu's visit to the White House.

Iran army head: We won't need more than 11 days to destroy Israel [MEMRI].

Panetta was reportedly dispatched here to read the government the riot act. Israel, he reportedly told his interlocutors, must not attack Iran without first receiving permission from Washington. Moreover, Israel should keep its mouth shut about attacking Iran. As far as Washington is concerned, Iran's latest threats to destroy Israel were nothing more than payback for statements by Netanyahu and other senior Israeli officials regarding Israel's refusal to countenance a nuclear armed Iran.

Over the past several weeks, we have learned that the administration has made its peace with Iran's nuclear aspirations. Senior administration officials acknowledge as much in off-record briefings. It is true, they say, that Iran may exploit its future talks with the US to run down the clock before they test a nuclear weapon. But, they add, if that happens, the US will simply have to live with a nuclear-armed mullocracy.

The administration's nonchalance about the threat of a nuclear armed Iran explains why the White House is so up in arms about the prospect of Israel acting independently to prevent Iran from building a nuclear arsenal. As far as the administration is concerned, the only reason Iran would threaten US interests is if Israel provokes it. As far as the administration is concerned, if Israel could just leave Iran's nuclear installations alone, Iran would behave itself. But if Israel preemptively takes out Iran's nuclear capabilities, and Iran in turn attacks Israeli and US targets in the region, the Obama administration will hold Israel - not Iran - responsible for whatever losses the US incurs. That was apparently the message Panetta wanted to transmit to Jerusalem during his recent visit.

WHILE LARGELY supported by the US media, the administration's view of the Iranian threat is not without its domestic critics. Opponents of the administration's policy of engagement and appeasement have pointed out that a nuclear armed Iran will surely destabilize the Middle East and as a consequence, will harm US national security interests. And this is true enough. Whether by spurring a regional nuclear arms race; destabilizing with the intent of overthrowing Western-aligned regimes in Egypt, Iraq, Jordan, Saudi Arabia, Kuwait, Bahrain and Morocco; enabling its terror proxies in Hizbullah and Hamas to operate under its nuclear umbrella; or attacking Israel with nuclear weapons, it is clear that the emergence of Iran as a nuclear power will cause tragedy, grief, chronic war and instability throughout the region. And - as the administration's critics make clear - such a state of affairs would be antithetical to US national interests.

While correct, these warnings miss the mark. Yes, it is true that a nuclear-armed Iran would destabilize the Middle East. But the Obama White House doesn't seem to care about that. What interests the White House apparently, is minimizing Teheran's animosity towards Washington. If it can convince the mullocracy that Washington is not a threat, then - the thinking goes - perhaps, the buck will stop at the Mediterranean Sea and the Persian Gulf.

This bit of wishful thinking is wrong both theoretically and practically. It fails to take into account Iran's stated intentions and the consequences of its likely behavior for the Middle East, and it ignores the fact that Iran's intentions and actions for the past two decades have not been limited to the Middle East.

For upwards of 20 years, and at a break-neck pace since 1999, Iran has built up a long strategic arm in America's backyard from which it is fully capable of attacking the US directly with the able and enthusiastic assistance of a network of proxies and allies.

IRAN POSES a direct threat to US national security through its alliances and military, intelligence and terrorist presence in South and Central America. Today Iranian Revolutionary Guards, Iran's Hizbullah terror cells, and other Iranian agencies operate in open collaboration with anti-US governments throughout the Western Hemisphere. The South American lynchpin of this new and growing Iranian-centered alliance system is Hugo Chavez's regime in Venezuela.

Through Chavez's good offices, Iran has developed a strategic presence in Nicaragua, Ecuador, and Bolivia and warm ties with Cuba. It is exerting growing influence in El Salvador, Brazil, Argentina, Peru and among FARC terrorists in Colombia. And it has highly developed and already proven human smuggling routes to the US in Mexico. It is through this alliance structure with anti-American regimes in Latin America and with sub-national Islamic and narco-terrorist networks in failing states that Iran already constitutes a grave threat to US national security. And it is through this rapidly expanding alliance system that a nuclear-armed Iran would pose an acute danger to US national security.

So far, the Obama administration has dealt with the threat posed by Iran's strategic alliance with Venezuela and Chavez's string of allied regimes in the same fashion as it has contended with Iran itself: It has blamed the situation on the Bush administration. As Secretary of State Hillary Clinton put it last week, the Bush administration's policy of "isolating leaders who have led the opposition to US policies in Central and Latin America has failed and marginalized Washington's interests."

CLINTON'S STATEMENT makes clear the basic and disturbing consistency of the administration's failure to understand that there are regimes that are inherently hostile to the US and will remain irreconcilably hostile to the US regardless of what it does or who sits in the White House. Just as the administration cannot get its arms around the fact that the Iranian regime can only justify its existence by maintaining its hostility towards America, so it cannot countenance the fact that Chavez is only able to justify his existence through his hatred for Uncle Sam. It has no way of explaining for instance the fact that Iran and Venezuela responded to Obama's attempts last month to extend an open hand to both countries by signing a memorandum upgrading their military alliance.
