Satmar chasidim are well aware that the medina prevents the geulah, but we have absolutely no right to endanger yidden to bring the geulah. Same way we can’t kill or endanger jews who are guilty of lashon hora/sinas chinam, which is the main prevention of the geulah.
It just means we’ll have to wait even longer, perhaps; or maybe Hashem will be choser tachas kisei kvodo and go lifnin mishuras hadin and bring the geulah anyway.
