Critics have accused PM Netanyahu of being slow to condemn extremism and anti-Semitism at US far-right protests, having only done so in a single tweet- three days after the rally in the Virginia town that ended in bloodshed.
Mr Ayoob Kara, the communications minister and a vocal Netanyahu supporter, said in remarks published Friday in the Jerusalem Post that backing President Trump was a strategic must for Israel's right-wing government.
"Due to the terrific relations with the US, we need to put the declarations about the Nazis in the proper proportion," Mr Kara told the English-language newspaper.
"We need to condemn anti-Semitism and any trace of Nazism, and I will do what I can as a minister to stop its spread. But Trump is the best US leader Israel has ever had," he said.
"His relations with the prime minister of Israel are wonderful, and after enduring the terrible years of (Barack) Obama, Trump is the unquestioned leader of the free world, and we must not accept anyone harming him," he added.
PM Netanyahu regularly speaks out against anti-Semitism in other countries, but the United States is Israel's most important ally, providing it with more than $3 billion per year in defence aid as well as key diplomatic backing.
The protests last weekend saw neo-Nazis and white supremacists protesting outside a synagogue, chanting anti-Semitic slogans and giving the Nazi salute.
On Tuesday, PM Netanyahu released his only response so far to the rally.
"Outraged by expressions of anti-Semitism, neo-Nazism and racism. Everyone should oppose this hatred," the Jewish state's premier posted in English.
President Trump has since reiterated earlier controversial claims that there was fault on "both sides," but PM Netanyahu has not commented further.
President Trump's arrival in office in January was saluted by Netanyahu's government, considered the most right wing in Israel's history, after a testy eight years with his predecessor Obama who often pressured the Prime Minister over Jewish settlement building in the occupied West Bank.
