US President Donald Trump is facing serious problems with the Iran campaign, failing to clearly articulate goals and an exit strategy for the conflict.

A senior counterterrorism official resigned, stating that Iran poses no "immediate threat" to the United States. Trump claims Iran has been "decimated" but avoids declaring victory.

Oil prices continue to rise amid instability in the region. European partners have declined to provide assistance in the Persian Gulf. Germany's chancellor stated that NATO involvement would be inappropriate, leaving Trump without key allied support.
