Trump briefly looks "Presidential" and "strong" and it is something he can do to stand up to Russia that is superficially good but meaningless. Russia can continue to do what it wants. Hell, if hypothetically if every runway was destroyed Russian planes would still be enough. Until every runway is levelled along with infrastructure and the Rebels are given SAMs it will at best impede.

Putin can even get all shouty and both sides can look great to their admirers - a strong man standoff.

The USA will struggle to have a follow up that will sort out the quagmire - Russia is lucky as all they want is warm water ports and specific influence with no interest in the locals. The West has such high standards they are all but impossible since most of the locals are unclear what a resolution looks like.
