This also begs the question would President Obama allow Her Majesty’s Navy to re-supply on Ascencion Island as President Reagan did?

That kinda depends on how much he wants continued access to the airbase there.

In 1982 a British task force used Ascension Island as a staging post during the Falklands War,[3] though according to Matthew Parris,[8] “...at the start of the Falklands conflict Washington at first refused Britain permission to use the USA-operated airfield facilities for refuelling RAF jets. Only after Mrs Thatcher intervened with Ronald Reagan did the Americans reluctantly concede.”
