On the eve of the US mid-term elections, the war with Iran still has an uncertain future. The negotiations between Tehran and Washington to end the conflicts were not successful and tensions in the region continue.

US President Donald Trump has said he will not launch a ground attack on Iran before the Nov. 3 election, but the rise in oil prices and the economic consequences of the war have put his administration under pressure in the final weeks of the Republican election campaign.

In American political culture, the development that takes place in the last weeks of the election campaign and can change the equation has a familiar name: "October Surprise".

This term has been applied to various events in recent decades; From the announcement of the imminent end of a war to the disclosure of candidate scandals, the publication of confidential information or an unexpected decision by a government body.
