The Trump Administration has spent the past month ringing alarm bells over what it has called “troubling, escalatory and dangerous” behavior by Iran. Yet government officials have shown very little evidence to the American public about that supposed threat.

The Pentagon said Friday additional troops and firepower are headed to the Middle East, marking the latest move by the Trump Administration to boost the American arsenal in the region by air, land and sea. Meanwhile, in another effort to deter Iran, the State Department issued an emergency notification in order to move forward with $8.1 billion in weapons sales to Saudi Arabia and other Arab allies, despite Congressional objections.

The U.S. has been headed on a collision course with Iran ever since President Donald Trump walked away from a multilateral nuclear deal a year ago. The Administration’s increasing pressure on Tehran has resulted in an unpredictable and tense standoff with potentially serious implications that has already moved beyond fiery rhetoric.
