Observers of developments in the Middle East have long taken it as a given that the United States and Israel are seeking for an excuse to attack Iran. The recently terminated conference in Warsaw had that objective, which was clearly expressed by Israeli Prime Minister Benjamin Netanyahu, but it failed to rally European and Middle Eastern states to support the cause. On the contrary, there was strong sentiment coming from Europe in particular that normalizing relations with Iran within the context of the 2015 multi party nuclear agreement is the preferred way to go both to avoid a major war and to prevent nuclear weapons proliferation.
There are foundations in Washington, all closely linked to Israel and its lobby in the U.S., that are wholly dedicated to making the case for war against Iran. They seek pretexts in various dark corners, including claims that Iran is cheating on its nuclear program, that it is developing ballistic missiles that will enable it to deliver its secret nuclear warheads onto targets in Europe and even the United States, that it is an oppressive, dictatorial government that must be subjected to regime change to liberate the Iranian people and give them democracy, and, most stridently, that is provoking and supporting wars and threats against U.S. allies all throughout the Middle East.
Dissecting the claims about Iran, one might reasonably counter that rigorous inspections by the United Nations International Atomic Energy Agency (IAEA) confirm that Tehran has no nuclear weapons program, a view that is supported by the U.S. intelligence community in its recent Worldwide Threat Assessment. Beyond that, Iran’s limited missile program can be regarded as largely defensive given the constant threats from Israel and the U.S. and one might well accept that the removal of the Iranian government is a task best suited for the Iranian people, not delivered through military intervention by a foreign power that has been starving the country through economic warfare. And as for provoking wars in the Middle East, look to the United States and Israel, not Iran.
So the hawks in Washington, by which one means National Security Adviser John Bolton, Secretary of State Mike Pompeo and, apparently President Donald Trump himself when the subject is Iran, have been somewhat frustrated by the lack of a clear casus belli to hang their war on.
