Yet Trump has furthered weakened the US position through his kowtowing to Russia. Attention in Washington is focused on Russian subversion of the 2016 presidential election and possible collusion. The furore has obscured Russia’s many malign activities elsewhere, notably in Syria. Trump’s irrelevance will be highlighted on Friday when Iran hosts a summit in Tehran with Russia and Turkey to discuss a “phased” Idlib offensive and what Moscow calls “long-term normalisation” in postwar Syria. The US is not at the table. Its views on Idlib or the country’s future will not be heard.
