[Japanese Prime Minister Shinzo] Abe met Iranian leaders on Wednesday and Thursday in a high-stakes attempt to defuse rising tensions between Iran and the United States. But the scale of the task he faced was undermined when two tankers, including one owned by a Japanese shipping company, were attacked in the Strait of Hormuz on Thursday.

[Iran’s Supreme Leader Ayatollah Ali] Khamenei was quoted by Iranian state media as saying President Trump is not “worthy” of exchanging messages with, and that Iran would not repeat its “bitter experience” of negotiating with the United States.

Secretary of State Mike Pompeo blamed Iran for the “blatant assault” on the vessels and said the United States would defend itself and its allies against Iranian aggression in the region. The Iranian mission at the United Nations denied any involvement and called the U.S. claim “inflammatory” and “Iranophobic.”

Michael Bosack, a special adviser at the Yokosuka Council on Asia-Pacific Studies in Japan, said it was too early to say who had carried out the attack or whether Japan was targeted.

Too early or not, Pompeo is going with the claim, and there's not much chance anyone in the US will argue with him.

Hours after two oil tankers were hit in a suspected attack in international waters of the Gulf of Oman, Secretary of State Mike Pompeo blamed Iran. He did not offer any evidence that Iran was responsible for the attack, pointing instead to intelligence, the weapons used and recent Iranian attacks on other targets.

Central Command spokesman Lt. Col. Earl Brown released a statement Thursday that said, "The U.S. and our partners in the region will take all necessary measures to defend ourselves and our interests. Today's attacks are a clear threat to international freedom of navigation and freedom of commerce."

"We have no interest in engaging in a new conflict in the Middle East," he added. "We will defend our interests, but a war with Iran is not in our strategic interest, nor in the best interest of the international community."

Speaking to reporters at the State Department in Washington, Pompeo said Iran is using "terror, bloodshed and extortion" in an attempt to pressure the U.S. to ease what he described as a "maximum pressure" campaign against Iran.

"Taken as a whole, these unprovoked attacks present a clear threat to international peace and security, a blatant assault on the freedom of navigation, and an unacceptable campaign of escalating tension by Iran," Pompeo said.

Pompeo provided no specifics about any planned response and took no questions from reporters.

So just what is it the big fool wants to do?

American officials are also calling for Iran to behave like a "normal" nation.

I don't even need to say it.
