From the Open Letter of Rav Shafran of the Aguda:
We must ensure that Israel is not used as a political weapon.
We must oppose efforts to turn support for Israel from a broad consensus into a wedge issue. Although we may rightly be concerned about trends regarding Israel in some corners, indicting an entire party as anti-Israel is not only inaccurate but has the potential of becoming a self-fulfilling prophecy. Nor should any party’s strong support for Israel become a justification to blindly support its politicians in every other matter. We should advocate for Israel’s security and other needs without painting ourselves into a partisan corner.
We should vote as Jews, not partisans.
