Like you said there are far more important things for us to work on, like pulling young people out of drug abuse, elimination any homelessness directly related to poverty, fighting gangland crap, punishing criminals properly, company for the elderly, healthcare for the poor, better education for our kids, anything that helps normal people lead a happier life.
Not peace in the middle east, not ending corruption in Africa, not ending terrorism. Impossible things.
Close the walls and really help those we can.
