You know what? Even if 1600 rockets (you forgot to say over how many years) were fired from the UK on US soil, even if "terrorists" were firing them, and even if the UK government had done nothing about it, still I would say, NO, the American poupulation would not approve of OBLITERATING the UK civilian population and infrastructure.
That is, if your facts are right, which they are not.
What do you see on television? Nothing, if you live in the US. Try going to other TV channels, or websites, including US allies website, like British press, or even Israel. You'd be shocked about what you don't see.
The pro-Israeli Americans are still denying that Israel bombed Red Cross ambulances when Israel is already investigating that incident.
You are the misinformed, and ultimately, the assassin.
In this county, patriotism does not require backing one's president. Where did you come up with that? And it most certainly does not require backing another country's savagery, notwithstanding it being a so called ally, israel.
