Every empire falls. Its collapse becomes inevitable once its rulers lose all sense of how absurd and abhorrent they have become

There is only one country in the world right now, in the midst of Israel’s slaughter in Gaza, where Prime Minister Benjamin Netanyahu is guaranteed dozens of standing ovations from the vast majority of its elected representatives.

That country is not Israel, where he has been a hugely divisive figure for many years. It is the United States.

On Wednesday, Netanyahu was back-slapped, glad-handed, whooped and cheered as he slowly made his way - hailed at every step as a conquering hero - to the podium of the US Congress.

This was the same Netanyahu who has overseen during the past 10 months the slaughter - so far - of some 40,000 Palestinians, around half of them women and children. More than 21,000 other children are reported missing, most of them likely dead under rubble.

It was the same Netanyahu whose government is standing trial for committing what the ICJ, the world’s highest judicial body, has termed a “plausible genocide”.

And yet, there was just one visible protester in the congressional chamber. Rashida Tlaib, the only US legislator of Palestinian heritage, sat silently grasping a small black sign. On one side it said: “War criminal”. On the other: “Guilty of genocide.”

One person among hundreds mutely trying to point out that the emperor was naked.

Indeed, the optics were stark.

This looked less like a visit by a foreign leader than a decorated elder general being welcomed back to the Senate in ancient Rome, or a grey-haired British viceroy from India embraced in the motherland’s parliament, after brutally subduing the “barbarians” on the fringes of empire.

This was a scene familiar from history books: of imperial brutality and colonial savagery, recast by the seat of the imperium as valour, honour, civilisation. And it looked every bit as absurd, and abhorrent, as it does when we look back on what happened 200 or 2,000 years ago.
