Rav E.S. Shick Shlit"a on the Matzav
Ladaat has an article that shows a letter that Rav Eliezer Shlomo Shick sent to his Hasidim. Summarized, it says that we need to preempt the upcoming war with Tefillot - in particular Tehillim 83. Also, we need to create unity, which cancels evil decrees and allows us to merit Geula. We need to stay away from arguments, and anyone who feels the need to continue arguments should get out of his community and find a community that befits him.
By having unity among ourselves and shunning arguments, this will cause the other nations to fear us and be busy fighting against each other, and leave us alone.
Fortunate is one who brings these words into his heart, to whom all his days will be good, and he will have a portion in the redemption of Israel.
