Like Lucy with the football, President Donald Trump keeps teasing that a deal to end the war with Iran is nearly over.

It’s one of a series of Iran talking points he has been repeating for months.

The war itself has changed — evolving from one of shock and awe to a monthlong ceasefire in which each side has imposed a costly blockade on the other.

But Trump’s talking points have stayed the same. The ideas he repeats include the key points that the US is in charge; Iran’s military is devastated; and things are going to be over pretty soon.

All this makes it very difficult to know how seriously to take his assurances about the proximity of a deal.
