Will the US be able to make a coalition against Iran?

Actually, since the beginning of his second presidential term, Donald Trump has regularly taken a confrontational attitude towards the US allies to date. In any situations, this has a tangible effect, as illustrated by the NATO summit in The Hague, where Trump's policy has undoubtedly contributed to the final decision to increase arms spending in the associate States.
