It looks like CentreRight was well represented at the End Hamas Terror rally. Douglas gave a great speech. I met Peter Cuthbertson in the crowd and plenty of the commenters in Rob Halfon's post appear to have been at the rally. The event was well organised and very well attended. Apart from some anti-Israel protesters causing trouble for the police, it was genuinely peaceful and included an appeal to text and make a donation to save lives in Israel and Gaza.
It was made clear at every step that the enemy was Hamas, which put Israel in a position where it had to act to defend its citizens. This quote, from Golda Meir after the Six-Day War in 1967, sums it up: "When peace comes we will perhaps in time be able to forgive the Arabs for killing our sons, but it will be harder for us to forgive them for having forced us to kill their sons."
