I wonder what Raheel Shareef is doing nowadays for Islamic nations as a leader of Islamic NATO. That is another farce.Nobody is talking about taking unliateral actions. The fact is if there was a coalition of Muslim countries, like that organisation Raheel Sharif is taking pay cheques for, then military intervention is entirely possible.
Also supporting the Palestinians with arms is completely legal. UN resolution 3246 recgnises the right of the Palestinians to resist occupation through any means including armed struggle.
