Rav Berland Shlit"a: War on 22 Av
According to YNet, Rav Eliezer Berland Shlit"a, one of the elder Breslov rabbis, told his students to travel to Uman and pray for Am Yisrael until the 22nd of Av (the night of August 1st, 2010), which is when war with Iran is supposed to break out.
One of his students said that the rav only meant this to be Mehazeik his students (i.e. to strengthen them in Avodat Hashem) - not that he believes it to be true.
Meanwhile, the "Milkman" said that all signs are pointing toward war, and we must pray for Am Yisrael to avoid it.
