What US midterm elections mean for Ukraine, Iran and elsewhere

The outcome of the midterm elections will shape US policy for years — and have repercussions around the globe. Decisions made in Washington affect both US adversaries such as Iran and countries such as Ukraine , which is seeking more support from the United States. President Donald Trump does not have the final say when it comes to deciding where the United States goes to war or which countries get financial or military aid. While the president wields more power in the US than in parliamentary democracies such as Germany, he does not govern alone — even in the land of opportunity. The House of Representatives and the Senate, the two chambers of Congress whose composition voters will decide this Tuesday, wield considerable influence.
