London has a murder epidemic and an incompetent Mayor but the Brits are too worried about image to tackle a crime wave or say that the Mayor is no good. What that means is that tourists should avoid the UK just as they already avoid Paris. If they hate Trump, they will hate average Americans, also.
My grandaughter was working as an au pair in Paris when thje attacks took place, She was supposed to meet some friends in the restaurant that was attacked but only one was free to go that day. He was uninjured.
The American au pairs all scarpered back home but the British, Germans and other girls mostly stayed. Just shows who has backbone, that include you.
