but he's also creating another trap for himself further down the line - if all he's going to do is allow other people (however construed) to decide policy, and in a number of fields set policies that are diametrically opposed to not just his stated and long held views, but views he actually campaigned on, then the people who voted for him will ask what the point of electing him was.
if Labour, assuming Corbyn is still there - and its not clear if thats his plan - go into the 2020 election on a manifesto of remaining in NATO, retaining Trident and pushing through Successor (as an example of policies he is known to oppose, but his party favours), then the 'is this credible?' question will be asked, and the answer is that its not.
