One of the many confusing Middle East events in recent weeks has been the way Iran attacked Arab countries in the region. Why so ? Doesn’t it have enough enemies, with the US blowing to pieces their Supreme Leader, Ayatollah Alikhameni, as well as Iran’s army chief of staff, its defence minister, the Revolutionary Guard  commander and a senior national security adviser?  By all the normal rules, that should have reduced Iran to its knees, clutching a white flag and begging the US to stop.
