Iranian threat to America and the reason

Iranian Defense Minister Brigadier General Mohammad Reza Ashtiani warned the United States of America of the consequences of unloading a detained tanker carrying Iranian oil.
Ashtiani said, “Tehran has the ability to carry out similar moves,” stressing that “unloading the detained Iranian oil shipment amounts to piracy and will be responded to.”
Last month, the Iranian Ministry of Foreign Affairs described the US move to seize an Iranian oil tanker as fruitless
The Iranian Foreign Ministry spokesman, Nasser Kanaani, announced in a press conference, “Tehran summoned the Swiss Chargé d’Affairs, in his capacity as the sponsor of American interests in Iran, to protest against the background of the seizure of the Iranian oil shipment.”
The United States is strengthening its existing forces in the region, as it announced last month its intention to deploy a destroyer and F-35 and F-16 warplanes, in addition to a collective readiness group, and a naval unit that includes about 3,000 people.
US military forces say that Iran has seized or attempted to seize control of nearly 20 international ships in the region over the past two years.
Washington also announced that its forces prevented two attempts by Iran to seize commercial oil tankers in international waters off Oman, on July 5.
The Iranian Navy, affiliated with the Iranian Revolutionary Guard, announced that America was mobilizing its forces in the Gulf waters to prevent stopping a ship that was smuggling Iranian fuel.
The Commander of the Naval Forces of the Revolutionary Guards, Admiral Ali Reza Tangsiri, said, “Two A-10 fighters, designated for close combat, carried out dangerous and completely unprofessional behavior, and then a helicopter, a drone, and another manned aircraft were sent to the area where we were searching.” The ship was in it, but our fighters detained the ship
