"If having expertise sophisticated enough to conduct the attack could be a reason to conclude that the attacker was Iran, "That would apply to the United States and Israel as well," said a source at the Foreign Ministry."

Israel has a proven history of using false attacks to start wars between countries. Iran has never started a war.

In 2005 Israel publicly acknowledged carrying out a 1954 attack on American targets in the Middle East, known as the Lavon Affair, in which Israeli operatives planted bombs which were then falsely blamed on the Muslim Brotherhood. https://en.wikipedia.org/wiki/Lavon_Affair

 in 1967 the crew of a US surveillance ship, the USS Liberty, say a 75 minute attack by Israeli warplanes was deliberate. The attack fired hundreds of rounds of cannon fire, rockets, napalm, machine-gun fire at lifeboats, and a torpedo from an Israeli patrol boat. It has been opined by former Chairman of the Joint Chiefs of Staff, Navy Admiral Thomas Moorer, that the attack may have been intended to draw the US into war with Egypt.

The Israeli newspaper Haraatz on last May 20th ran an article entitled "Netanyahu's Iran Dilemma: Getting Trump to Act Without Putting Israel on the Front Line." The article said:

"Even if Trump's instinct tells him it's best to avoid war with Iran, no one can be certain of his intentions - not even Netanyahu."

The Israeli secret service, the Mossad, previously proclaimed the slogan "by way of deception thou shalt make war." It has been changed to “without deception, a nation falls.”

In 2007, former commander of NATO and former presidential candidate General Wes Clark made waves when he told an audience that a series of regime changes had been planned by the Pentagon since even before the invasion of Iraq. Clark said a general within the Bush Administration told him before the invasion. Clark said:

And he said, "This is a memo that describes how we're going to take out seven countries in five years, starting with Iraq, and then Syria, Lebanon, Libya, Somalia, Sudan and, finishing off, Iran."

EVERYTHING points to Israel.
