A painting of Lord Balfour housed at the University of Cambridge’s Trinity College was slashed by protest group Palestine Action.
The painting of Lord Balfour was made in 1914 by Philip Alexius de László inside Trinity College. The Palestine Action group specifically targeted the Lord Balfour painting, describing his declaration as the beginning of “ethnic cleansing of Palestine by promising the land away—which the British never had the right to do.”
It was “just a letter” written on behalf of the British state giving their full support for the creation of Israel in what was, at the time, British-occupied Ottoman land that the British had already promised to return to the Palestinian people.
So yes, the British literally give the land - which was not theirs in any legitimate form - to a group other than the native population.
They then provided (and continue to provide) financial, political and military support for decades, while Palestine was progressively colonised.
