President Biden has presided over disasters worldwide, from his bungled Afghanistan pullout to his invitation of Russian President Vladimir Putin’s invasion of Ukraine, that have exposed our citizens to a potential nuclear war.

His administration has not only projected weakness to the world but weakened America — at home and abroad — frittering away the commanding strategic position the Trump administration had bequeathed it and opening the door to aggression from our greatest foreign adversary of all, Communist China, that could well culminate in its long-desired invasion of Taiwan.

What distinguishes the massacre unfolding in Israel, in the rapes, murders and hostage-taking of its people by the Jew-hating, genocidal jihadist group Hamas, is the Biden administration’s unique culpability in the barbaric assault and in empowering the theocratic regime behind it.

That Israel, a state that’s suffered under the perpetual threat of annihilation, just experienced its darkest day in the last 50 years is the residue of Biden’s design — an extension of President Barack Obama’s design — on making Iran the “strong horse” in the Middle East.

The Biden administration has served as the aider, abettor and enabler of the world’s leading state sponsor of terror, Iran — both by backing the mullocracy in pursuit of an empty nuclear weapons deal and concurrently putting the screws to the Jewish state, Israel, that the Islamic supremacists seek to obliterate.

In so doing, the Biden team has proven the leading sponsor of the world’s leading state sponsor of terror, without which Hamas’ assault could never have occurred.

Consider how the Biden administration has strengthened Iran and its proxies while weakening Israel, thereby contributing to Hamas’ war on Israel:

We have no idea the extent to which the Biden administration, filled with like-minded ideologues, has been infiltrated by other Iranian agents and their allies.

To what end? Is there any nexus to the ongoing attacks on Israel and those that could come elsewhere, including on our streets?

Biden’s platitudes about support for Israel mean nothing when contrasted with these actions.

Israel’s enemies exploited them, initiating what is sure to be a grisly and grinding war that could easily expand into a regional if not global conflagration.

In this calamity, like none among those for which Biden bears culpability, the blood of Israelis and Americans slaughtered or being held hostage is on his hands.
