evidence: The biggest change to Israel's frontiers came in 1967, when the conflict known as the Six Day War left Israel in occupation of the Sinai peninsula, the Gaza Strip, the West Bank, East Jerusalem and most of the Syrian Golan Heights - effectively tripling the size of territory under Israel's control. Israel effectively annexed East Jerusalem - claiming the whole of the city as its capital - and the Golan Heights. These moves were not recognised by the international community, until the US changed its official position on the matter under the Trump administration, becoming the first major power to do so. Overwhelmingly, international opinion continues to consider East Jerusalem and the Golan Heights as occupied territory. [...] The final status and contours of the West Bank, Gaza and East Jerusalem are meant to be decided in negotiations between Israel and the Palestinians living there under Israeli occupation, but decades of on-off talks have so far proved fruitless.
