Hamas intended to provoke a massive reaction by Israel. It intended to kill as many peope as possible in the most savage ways imaginable, but it always wants as many deaths of Gazans as possible and will work to ensure that's the case by preventing people from leaving northern Gaza, thereby enlisting them as human shields.

The game is to leverage public opinion in their favour so that Israel bows to international pressure and pulls back from its mission to deny Hamas a base of operations. Thus, though not everyone who was at demonstrations yesterday was a Hamas supporter, they are Hamas's useful idiots.

Only reluctantly do I conclude that Israel must fight Hamas inside Gaza. It's no small thing to drive a million people out of their homes. But in the final analysis, Gaza will always be a beachhead for Islamist operations, and Gazan residents and Israelis will always suffer the consequences.

There are only two basic options here. Either return to the status quo, in which Hamas is able to launch indiscriminate rocket attacks on Israel, forcing Israel to maintain a blockade that keeps Gaza in poverty, or to simply drain the sea Hamas swims in.

Those who would have Israel abandon its military action are pushing for the status quo in which Hamas is able to continue its racist terror campaign, and for Gaza to remain a dysfunctional and institutionally corrupt enclave - sustained by bad faith actors with the sole motive of destabilising the region and demonising Israel in the eyes of the world.

Sadly, a military operation in Gaza will have civilian casualties. It's inevitable consequences of a war that Hamas started. It is also a consequence of Hamas using Gazans a human shield. The aim is to blackmail Israel into leniency so Hamas can continue to operate. Israel is obliged to do all it can to prevent civilian casualties, and does so within the limitation of the situation. Hamas does not. But Israel, like any nation state, must put the lives and property of its own citizens first. No other country would be asked to compromise on that.

Some British nationalists argue that this is not our fight. But they are wrong. Islamism is the enemy. It is the enemy wherever we find it; whether it's in Gaza, Iran, Pakistan, London or Oldham. We must carve it out wherever we find it. There is no accomodation to be reached with this murderous ideology. Moreover, we stand for the sovereignty of the nation state, and a nation's right to self-defence.

As much as anything, proudly declaring our support for Israel is a message to foreigners in our lands that these are the values we will fight for, home and abroad. Let them come out on the streets in protest. Let's see who they are - and mark them well. And let us vote accordingly so that these people are promptly removed and do not threaten us.

We have already allowed too many to make our lands their home. We already face a fight to reclaim our cities and our capital. This weekend underscores once and for all that multiculturalism has failed and must be reversed. If our political establishment will not do as instructed, we must consider them part of the problem and an aid to the enemy. We only have a short time to reclaim our country through peaceful means.
