Writing on the embassy website, Mr Bachman said:"This date is symbolic, it was the 29 November 1947 when the by the United Nations General Assembly officially recognized the state of Israel."
"This date demonstrates Israel's willingness to compromise, when Israel accepted the partition plan, while the Palestinians rejected it. Something they continue to do to this day, including all attempts to reach a peace agreement."
Isaac Bachman was called home to Israel three weeks ago in protest against Sweden's official recognition of a Palestinian state.
In parliament on Thursday, Sweden's foreign minister Margot Wallström answered opposition criticism to say it was "right, right, right" of the government to recognise the state of Palestine. The terror in Jerusalem the other day she said, did not change that view.
Hans Wallmark of the Moderate party said that the foundations of the government's decision to recognize Palestine was "wrong, wrong, wrong".
