The problem for Israel is that several other countries perform much better than they used to , like Turkey. In Israel math education is far better than Turkey, as are the teachers. Yet the very cream of the Turkish students are usually better than the Israeli counterparts because in Turkey they are selected from a larger pool. Turkey does not spent even a one twentieth of what Israel spends for each student, so average education in Turkey is very bad but the best at the top can compete with anyone. Recreational math, chess and small math competitions are becoming very popular in Turkey, this was not so, say then years ago. Also, Turked loses its best minds to abroad and never manages to transfer them to science and tech in Turkey, Israel does a much better job in this because the existing science in Israel is very high level.
