the close of the Obama administration's 'carrot' phase of Iranian diplomacy":
It's impossible now for the United States to convince Iran that it doesn't need a nuclear weapon when the U.S. is helping to massively boost other militaries in the region. From an Iranian perspective, U.S. arms sales will only reinforce the notion that they need a nuclear weapon to offset the large and growing imbalance of conventional military power in the Middle East.
The good news is that the balance of power in the Gulf is stacked overwhelmingly against the Iranian regime.
The bad news is this won't stop Netanyahu from launching World War III.
