Poland's PM Mateusz Morawiecki issued Israel an ultimatum Monday, telling Tel-Aviv that if they didn't apologize for the comments, Poland would pull out of the V4 talks scheduled to take place in Jerusalem the following day.
The Times of Israel reported that, when asked for a response, Foreign Ministry spokesman Emmanuel Nahshon said he was unaware of such a meeting, and the Prime Minister's Office said it does "not comment on contacts with countries with which Israel does not have formal relations".
Poland's prime minister says his country is not sending a delegation to a meeting in Jerusalem after the acting Israeli foreign minister said that Poles "collaborated with the Nazis" and "sucked anti-Semitism from their mothers' milk".
Polish Foreign Minister Jacek Czaputowicz was due to replace Morawiecki, but a senior government official in Warsaw said today that this was now under a "question mark" following comments by Israel's diplomatic chief Israel Katz.
The Foreign Ministry also summoned the Israeli ambassador, Anna Azari, to demand a second set of clarifications in recent days.
These four countries, governed by right-wing parties, some of which are worrisomely associated with anti-Semitic groups, provide sound support to Netanyahu's government in its struggle against the ant-Zionist folks in Brussels. "As (former Israeli Prime Minister) Yitzhak Shamir said - his father was murdered by Poles - he said that from his point of view they sucked anti-Semitism with their mothers" milk.
Mateusz Morawiecki's decision to scotch Poland's involvement in the summit of central European nations comes after the latest salvo in a long row between Poland and Israel over history.
"Together with the prime minister we will continue to lead the State of Israel's foreign policy to new achievements", Katz, 63, said on Twitter.
The gathering began to unravel last week when Netanyahu, during a visit to Warsaw, told reporters that "Poles cooperated with the Nazis".
"Poles collaborated with the Nazis, definitely".
The leaders issued a statement Monday saying that accusing all Poles of anti-Semitism slighted thousands of Poles honored by Israel's Holocaust memorial center, Yad Vashem, for helping Jews during the Holocaust.
Lost in the diplomatic uproar was that Netanyahu was actually defending his close alliance with Poland and other eastern European leaders when he made the comments that offended the Poles.
It is also undeniable that Polish Jews perished at the hands of their non-Jewish neighbours in isolated cases.
However, Holocaust researchers have collected ample evidence of Polish villagers who murdered Jews fleeing the Nazis, or Polish blackmailers who preyed on helpless Jews for financial gain.
