Marco Rubio writes on his website:
I am alarmed that our long-standing solidarity with Israel has been thrown into doubt by a White House that seems to be playing a proverbial game of jump ball, whereby the world wonders on which side America will stand. Of course, we should stand with Israel. Doing otherwise sends a dangerously emboldening signal to Israel’s enemies. [...]
If Israel’s right to self-defense is undermined by misguided efforts to lift its legal and necessary blockade of Gaza, which serves to stop Hamas from arming itself with deadly weapons, there will be lasting consequences not only for Israel, but also for the U.S. and the entire world.
Whole thing here.
