"The US secretly agreed to give the Russians sensitive information on Britain’s nuclear deterrent to persuade them to sign a key treaty."

Says the UK Telegraph, relying on Wikileaks:

A series of classified messages sent to Washington by US negotiators show how information on Britain’s nuclear capability was crucial to securing Russia’s support for the “New START” deal.

Oh, but don't be upset! The START treaty was Obama's chosen post-elections showdown with GOP last fall:

Just two weeks after an election that left him struggling to find his way forward, President Obama has decided to confront Senate Republicans in a make-or-break battle over arms control that could be an early test of his mettle heading into the final two years of his term.

Obama proved his mettle! What's more important? Our relationship with the UK or proof of Obama's mettle after the crushing 2010 elections?
