The British action imo, is linked to the break in US-Israeli relations. Now that Obama is sending out clear diplomatic signals that this administration is becoming hostile to Israel, it’s a free for all in hammering Israel.
Pressure on Israel had ramped up immensely since the break began.
The quartet gave their dictum on Jerusalem, the arabs are becoming more entrenched and vocal, and the UK made a decision on this in the last week.
This will all end badly. It smells of appeasement to the arab/muslim world, and that only earns contempt, not friends, in that region.
