The Middle Eastern hot spots continued in 2019.After the Trump administration announced its withdrawal from the Iran and P5+1 nuclear agreement，America imposed economic sanctions and resorted to military deterrence against Iran. Tensions in the Gulf region heated up. The Trump administration officially acknowledged Israel’s sovereignty over the Golan Heights，abandoning its former position of maintaining a minimum level of neutrality in the Arab-Israeli conflict. A new round of armed conflicts took place in Libya，and it will be difficult to bring an end to the war within a short period of time. The Syrian war is coming to an end，but the process of peaceful reconstruction of the country faces many obstacles. The result of the Israel’s election is unclear. The political security situation in the Middle East is characterized by two major features：First，the Iran issue has become the core problem in the region，reflecting the irreconcilable structural contradictions between the United States and Iran. Second，the Trump administration’s involvement in Middle Eastern affairs has increased significantly，becoming the main driver behind the regional tensions.
