People in countries outside of the United States are shit scared of anything that Trump does in regard to foreign politics. For example. Recently he goes to Israel and lets the Israeli prime minister make Jerusalem the capital of Israel. There were enough tensions between them and the Palestinians as it was.
Just for clarification - Israel is considering moving their nations capital from Tel Aviv to Jerusalem. President Trump decided that if such an event occurs he would recognize Israel's decision by moving the US Embassy from Tel Aviv to Jerusalem.
Israel is a sovereign, recognized nation. President Trump did not let Israel do anything. Israel does as it pleases.
In addition, there will always be tensions between "Palestinians" and Israel as only Israel supports a two-state solution.
