Obama and Kerry have decided that the best way to be remembered is for a legacy of picking fights with the few remaining allies the US has. After attacking Israel, Kerry is back to bashing the UK.
Obama had already decided to blame the UK for his disastrous policy in Libya. Now Kerry is blaming the UK for Syria. This is after the UK criticized Kerry's attack on Israel.
The Obama foreign policy has turned into a frustrated malice. His team is lashing out at close allies even while they know their own impotence. The prime ministers of the UK and Israel have now made their disdain for Obama and Kerry, and their desire to work with Trump, very clear.
All that's left is for Kerry to snipe at them and blame them for his failures, before heading back to another bout of windsurfing at Nantucket.
