Rav Wein quotes Rav Kahaneman, “Rabbi
Yosef Kahaneman, the Ponevezher Rav, told me that he flew
the Israeli flag from the roof of his yeshivah building in Bnei
locals complained about this, he
answered them with the following: ‘I
flew the Lithuanian flag on the roof of
my yeshivah in Ponevezh on Lithuanian
Independence Day. My friends, it is no
worse here.'” http://www.ou.org/pdf/ja/5767/summer67/30_32_33.pdf
