Israeli Prime Minister Benjamin Netanyahu praised President Trump on Friday for approving the strike that killed top Iranian commander Qassem Soleimani after cutting short a visit to Greece to monitor the situation from Jerusalem.

“President Trump is worthy of full appreciation for acting swiftly, forcefully and decisively,” he told reporters before departing Greece to head back to Israel.

“We stand fully by the United States in its just battle for security, peace and self-defense,” Netanyahu said, adding that “just as Israel has the right of self-defense, the United States has exactly the same right.”

“Qassem Soleimani is responsible for the death of American citizens and many other innocent people. He was planning more such attacks,” he said.

Netanyahu had earlier instructed government officials not to comment about the killing and they also were mum on whether Israel had provided any intelligence or support for the mission.

Meanwhile, the Israeli Defense Ministry put the country’s embassies and offices on “high alert” across the globe amid Iranian threats of revenge against the US and the Jewish state for the killing of the powerful commander of the elite Quds Force.

An Israeli ski resort near the Syrian border that was the site of a previous missile attack was shuttered due to concerns of a possible strike, the Times of Israel reported.

Defense Minister Naftali Bennett also convened a meeting at the military headquarters in Tel Aviv of security and intelligence chiefs to deal with the possible repercussions of the Soleimani killing, according to the news outlet.

Netanyahu’s chief political opponent, Blue and White chief Benny Gantz, a former military chief of staff, also praised Trump for his “brave decision” to launch the strike.

“The killing of Soleimani is a message to all the head of global terror: on your own heads be it,” Gantz said. The assassination was “fitting for anyone whose action brings about the murder of innocents and the destabilization of the region and the world.”

On matters of national security, “there is no coalition and opposition,” he added.

Analysts said Israel was gearing up for possible reprisals from Iranian-backed Hezbollah in Lebanon in the north and the Gaza Strip in the south, where the ruling Hamas faction and Islamic Jihad cells had ties to Soleimani.

“Israel has to be on high alert,” Yossi Kupperwasser, a former chief of intelligence research for the Israeli army, told the Washington Post.

“These groups are all indebted to Soleimani. They might have to do something to show sympathy for him,” he said.

“He was busy, day in and day out, in promoting terrorist attacks again Israelis and training, arming and financing other groups to do the same,” Kupperwasser added. “Obviously, we have no sorrow for him.”

Ram Ben Barak, the former deputy director of the Mossad, Israel’s intelligence agency, said that Soleimani’s death was “a blow to the Quds Force.”

“There was almost no terror attack in the last 20 years that didn’t have Qassem Soleimani’s fingerprints on it,” Ben Barak told Israeli Army Radio. “The [Iranian] entrenchment in Syria, arming [the Lebanese Shiite militia] Hezbollah, the [Hezbollah] precision-guided missile project, contacts with Islamic Jihad in Gaza.

“There was almost nothing that happened that Soleimani wasn’t involved in actively,” he said, according to NPR. “He initiated, pushed and checked it was done.”

It was unclear what effect the killing would have on Israel’s political situation, but observers said Netanyahu might be relieved for any distraction during his attempts to have parliament shield him from a pending corruption prosecution.

“It could help in the short term if all the headlines aren’t about a craven request for immunity,” Chuck Freilich, a former Israeli deputy national security adviser, told The Washington Post. ‘

“If this escalates, it could be a negative,” he added.

Moshe Ya’alon, another former military chief of staff, said: “The world in general, and the Middle East in particular, has been freed from a mass murderer… Good riddance!”
