Terrorist organisations can't exist in a vacuum, of course there is much wider support, and of course that doesn't mean everyone in Gaza is included in that!!
What I don't understand is why the world is not collectively rising up to say we need to stamp out terrorism and extremism and we stand with all people against Hamas, Israel and all innocent Palestinian civilians. The Free Palestine and Isreal vs Palestine rhetoric is only helping the Hamas cause in my opinion. People who ascribe to this extreme Islamic ideology are never going to be de-radicalised and they are our enemy too.
