You should not have anxiety, is on the other side of the world for most of the west, also, most people are completely not involved. US sends money to Israel, Millions. Taxpayers money, and Europe sells weapons and other things. As such, we are still participating via our governments.
Not informing yourself about what happens around the world and what your government is responsible of may make you feel safe, but you are willingly hiding the truth to yourself. I won't judge your actions, I just hope you realise what you are doing.
