Washington can't organize anti-Iranian coalition
The U.S. called to unite to counter "Iranian aggression" and form coalition in Persian Gulf. But American allies and partners prefers to be staying far away from whatever the United States really intends. Till now South Korea only supported idea of the U.S. to form alliance for Persian Gulf.
The reason is simple. After Iran seized a British oil tanker on July 19, and Secretary of State Pompeo saying, “The responsibility in the first instance falls to the United Kingdom to take care of their ships” friends of the U.S. not care about strategic implications of Washington anymore. Most of European powers also not agree with the U.S. about sanctions against Iran.
Meanwhile Iran signed agreement with Russia for military cooperation on Monday, July 29. Iranian media informed that joint drills of navy will be organized soon in the Persian Gulf.
