The United States is sending about 3,000 additional troops to Saudi Arabia in the latest military response by the Trump administration after it accused Iran of attacks last month on Saudi oil facilities, the Pentagon said on Friday. The move came only five days after President Trump said that his desire to terminate America’s “endless wars” led to his decision to pull back from the border area between Syria and Turkey about 50 troops who were working to create a “safe zone” between Turkish and Kurdish troops.
