George Galloway answered this in this video, saying:

I was underground as an undercover agent of the ANC. I was working for Nelson Mandela's ANC. I gave my blood on the floor of the Gugulethu police station in Cape Town. Was the ANC a terrorist organization? the answer is no, even though they had people who carried out terrorist attacks. You have to understand the whole picture and not just a tiny corner of a single snapshot. The Palestinians are fighting against an apartheid state for the millions of Palestinians scattered around the world with no one speaking up for them. If you are fighting against occupation forces undoubtedly it is resistance. It was David Cameron I remind you who called it the largest open-air prison camp in the world. If you break through that and you start taking a toll on the guards, the people who've kept you in this absolute misery with regular death being dealt to you, then that's a legitimate act of resistance.

George Galloway responded to that question in this video by saying:

It was by no means the single biggest slaughter in the Israel-Palestine chapter. In fact, in five hours, with Sharon on the roof, shining a searchlight into the Sabra and Shatila camps in Beirut. 3,850 Palestinian women and children. There were only women and children because the men had all agreed to sail away to Tunisia as part of an American broker deal. Now, younger viewers will not remember Sabra and Shatila, but those two names are burned in the minds of those older and who care about it. So that’s triple the actual death toll on October the 7th. The fact that you thought, I mean, disrespectfully, that this was the biggest single day of slaughter is part of the problem. The blood of Palestinians is oftentimes by commentators and politicians regarded as less valuable than the blood of Israelis. All the blood is a disgrace, all of it.

George Galloway said in this video:

On the question of "Isn't it Hamas that started this?", Yes, but Israel would have known that if you keep 2.3 million people in a cage, they’re going to try and break out. So there’s all kinds of concomitants should have known in this story. They should have known when they occupied Palestinian land, drove hundreds of thousands of them out, never to return, that those people would have children, and they would have children, and enmity, bitterness, and the desire for revenge would exist forever. And so it has..

George Galloway mentioned in this video:

The solution should be within one state it will have to be, because the two-state solution, which I supported as an Arafatist, I look foolish now, having supported the Oslo Agreement, I look like an idiot. Arafat looks like an idiot. Because we believed that there would be a two-state solution, and almost 40 years after the agreement, there's not one centimetre of Palestine free, and Gaza is in complete ruins. The West Bank is on fire. Settlers are running amok. The attempt to ethnically cleanse the West Bank and East Jerusalem is running concurrently with the slaughter in Gaza. So where are you going to put two-state solutions? There's 800,000 illegal settlers in the West Bank. They all settled there long before October the 7th.

In 1948 the Balfour Declaration was received and co-signed by the Zionist organizations. I was literally in the building. It's a big Manchester story. Balfour himself was an MP in Manchester. The document was signed in Manchester. The reality is, when we promised, on behalf of one people, to give to a second people the land that belonged to a third people, we set off, as Churchill put it, down a descending staircase, soaked in blood. That's why when some people say, why are you so exercised by this? Because my country caused it, and my country is still involved in it. That's why I'm so exercised by it.
