Some journalists's job is to risk their life going to dangerous places. Going to the US is not yet being a war reporter but it's more risky than before.
I'm not defending the US actions here, but UK is even worse when it comes to criticizing Israel or free speech in general.
It was never fun to travel to the US, and the border agents have always been rude, unprofessional and arbitrary. But it seems like it has gotten much worse, and there is no way I'm traveling to the US these days.
