DONALD TRUMP’S threats to ethnically cleanse two million Palestinians from Gaza must be challenged at Saturday's national march in central London, Stop the War’s vice-chair Chris Nineham has said.

Speaking a day after pleading not guilty to breaking protest restrictions during the last Palestine demonstration, he warned that the US president’s threats of a “monstrous escalation” in the Middle East could lead to attacks on Greenland or Latin America.

“The Palestinans are the first target of the new regime and we therefore have to make absolutely certain that they don’t become his first victims,” he told the Morning Star.

“If people stand by and let Palestinians be treated in this catastrophic way then with Donald Trump everyone is in danger.

“It’s clear that Trump represents a new more naked, more confrontational, more aggressive form of capitalist and capitalist competition, and it’s absolutely vital that his ambitions and way of doing politics is challenged and decisively as quickly as can be.

“Be in no doubt Trump is capable of lashing out in a very, very dangerous and unpredictable way, so we need to be ready and organised.”

The veteran anti-war activist, 62, told of his relief after a district judge dropped police bail conditions banning him from attending marches organised by the Palestine Solidarity Campaign (PSC).

Facing trial after denying two counts of breaking the Public Order Act at Westminster magistrates’ court on Thursday, he said: “I’m very happy that my bail conditions were dropped yesterday.

“That means I can go on the demonstration, and I think tomorrow’s march is one of the most important demonstrations we have had since the beginning of the cycle.

“This is partly because it does come after an unprecedented attack on the right to protest on January 18 but also because we now face the situations where the US or Donald Trump is threatening a monstrous escalation in Israel’s assault on the Palestinians in Gaza.

“The problem is that Donald Trump is a mortal threat to the ceasefire and to the very existence of the population of Gaza and anyone who thinks that the situations has been resolved in any way is living in a dream world.

“Trump has threatened to remove the whole population from the Gaza Strip and against that background no ceasefire process can be taken seriously.

“Our government and the commentariat try to convince people that we are back to some sort of normalisation in the Middle East when it is palpable that the situation is more dangerous now than at many times it has been in last 16 months.

“This must be resisted by all means necessary, this must be resisted by the biggest showing of opposition on the streets tomorrow.”

PSC director Ben Jamal, who was arrested alongside Mr Nineham and is due to appear in court on Friday, expected Saturday’s march from Whitehall to the US embassy to be one of the largest shows of solidarity for Palestinians since Israel began its genocide.

He said: “For 16 months we have warned that Israel is seeking to erase the Palestinian people from the Gaza Strip and colonise the whole of historic Palestine.

“That Israel’s fugitive prime minister can be entertained by the US president while they both gleefully contemplate the ethnic cleansing of Gaza is a nauseating nadir in international politics.

“Our task is to redouble our efforts.

“Marching on the streets in our hundreds of thousands shows Palestinians we are with them and shows our government they cannot hide their complicity.

“Our strength and determination are growing and will not be deflected by political attacks or repressive policing.

“We uphold our democratic rights as we uphold international law and universal principles of freedom, justice and equality. Together, we will see a free Palestine.”

Today at the Munich Security Conference, Amnesty International secretary general Agnes Callamard warned of the “Donald Trump effect” on human rights around the world.

“In the case of Gaza, what we are witnessing is not even disruption … It is cruel destruction of a peace process that took months to be negotiated, that has reached a very fragile state,” she said.

“What Donald Trump has done is really fragilise it further and make phase two of that peace process extraordinarily difficult,” she said.

“It is a war crime to forcibly push people out of their places, and it could be a crime against humanity if it is well organised; in a nutshell, it amounts to ethnic cleansing if it was to be carried out.”
