Yes, that's when our meddling started...1917, and I think the following sums up quite well the further meddling by us and others....resulting in the current mess:
.
'It was extremist zionist groups like the Irgun and Lehi who aimed to establish a Jewish state (not just a homeland within the state) and turned to terrorism to establish this, attacking British forces e.g. bombing the King David hotel in 1946.
They also attacked many Palestinian civilians, and Palestinians fought back. The situation was in danger of turning into a civil war, and extra troops were sent to impose order.
A big problem was that many illegal Jewish immigrants from Europe tried to enter Palestine, many of them traumatised by WW II and in no mood to coexist peacefully with the locals. This greatly added to the conflict on the ground, so British authorities intercepted the ships and detained the migrants. This influx was organised by the Jewish Agency who refused to consider resettlement of refugees in the UK, Empire or USA. After a detainment camp was attacked and detainees released, they were detained in Cyprus instead.
However, the Truman administration of the USA demanded that these immigrants be allowed into Palestine, threatening economic sanctions. The UK, almost bankrupt after WW II, was in no position to refuse, agreeing to the demands of a joint commission, and this influx of immigrants indeed made the situation far worse on the ground.
To try to find a Plan B, the UK turned the problem over to the newly formed UN, and announced an intention to quit the territory in 1948. The UN drafted a partition plan, but this could not be agreed by the parties in Palestine, so the White Paper plan continued. The unrest escalated into virtual civil war, and the British became less able to cope, particularly as upcoming Indian independence and partition was drawing in so much manpower there.
The civil war included certain massacres of civilians, such as at Deir Yassin, and this caused a number of people in Palestine to flee the territory to neighbouring countries until the fighting would subside.
One day before the end of Mandate, Zionists declared Israel as a Jewish state, and the Truman administration recognised it 11 minutes later. By this time the British were in no position to stop it. Open war broke out, drawing in surrounding Arab countries and the Israelis were victorious on the battlefield. However, they "ethnically cleansed" almost 80% of Palestinians in the process.
By the time a ceasefire was arranged, Israeli forces controlled 78% of Palestine, far more than was allocated to a Jewish state under the UN partition plan.
Although these cease-fire lines were meant to be temporary pending a settlement, Israel has maintained them as borders ever since, even expanding into more territory. UN resolutions demanded that Israel allow the refugees to return to their homes and reclaim their property, but instead it has continuously refused and has even confiscated their property.
So, they weren't 'given' Palestine, Jewish extremists took it by force, ethnically cleansing the indigenous population. This continued dispossession is the underlying cause of all the conflict ever since.
It's an example of religiously-inspired extremism making the idea of "god gave us this land" take priority over normal secular citizenship and property rights, as well as international law.'
RELIGION and DO-GOODERS ....as usual.
