Seems to me like a strong, yet measured response.
According to the Washington Examiner:
The Pentagon is sending additional troops and missiles to Saudi Arabia in response to Iran’s attack on Saudi oil facilities last weekend.
“The president has approved the deployment of U.S. forces which are primarily defensive in nature,” Defense Secretary Mark Esper said in a surprise briefing Friday night. He said the kingdom had asked President Trump for the support.
“We are contributing to Saudi Arabia’s defense,” Chairman of the Joint Chiefs of Staff Marine Corps Gen. Joseph Dunford added.
Neither official would say how many troops the United States is contributing, but the number will likely be in the hundreds. Nothing is happening immediately, and Dunford said he will present more specifics next week.
Esper said U.S. and Saudi officials on the ground had confirmed the attack originated in Iran.
