The last time I was in London was just before the invasion of Europe began, and even back then the whole city it seems was full of Pakis, Indians, and Africans. You could still walk on the streets and not be unduly worried. I cannot even begin to imagine what its like there now that people are stabbing and throwing acid and other shit. Would not go back there.
POTUS needs to be careful. That British government is our enemy. The PM, the London Mayor, the Royal Family, all of them hate us and our president.
