Their attempts to fight back will only escalate the situation, and the carnage will continue.
Edit: I'm not advocating that we not support Israel. I'm simply stating a hard truth regarding "why they hate us".
Swedish Muslim terrorists also tried to create a massacre at Jyllandsposten because of their drawings (https://en.wikipedia.org/wiki/Jyllands-Posten_Muhammad_carto...).
These terrorists were born and raised in Sweden, had a better standard of living than me, studied engineering in university and had nothing to complain about. Sweden doesn't attack any countries, we love Palestine and dislike Israel (http://www.theguardian.com/world/2014/oct/30/sweden-official...) and we shelter 80-100,000 Muslim refugees/year. What should we do exactly? Jail all cartoonists and make it a crime to insult Islam?
