But Donald Trump's triumphant visit was not without its lighter — and embarrassing — side.

The first squirm came only moments after The Donald had stepped off Air Force One at Ben-Gurion airport.

As proud premier Benjamin Netanyahu marshalled his ministers and leading politicians to meet and greet the most powerful man on the planet, one of them broke ranks.

Knesset bad-boy Oren Hazan stepped out of the handshake queue . . . and snatched a selfie with the American president.

Netanyahu could hardly believe his eyes . . . nor contain his anger.

He glared as Hazan — a well-known Likud rabblerouser — grabbed Trump by the shoulder and put an arm around him for the picture.

Chutzpa? Vulgarity, more like.

Bibi even tried — in vain — to knock the shameless MP's hand away. Inevitably, the sensational snap appeared on Facebook and Twitter a short time later.

Could you ever imagine such a thing happening a day earlier when the leader of the free world was mingling with Muslim potentates in Saudi Arabia?

But Trump himself was guilty of an embarrassing incident as he de-planed in Tel Aviv.

The Israeli prime minister and his wife Sara showed what a close and loving couple they are by walking hand in hand on the tarmac's red carpet.

And taking his lead from them, Trump reached out for HIS wife's hand too.

But the First Lady would have none of it and chose not to respond.

However Donald, as the world knows, enjoys getting his own way and grabbed her hand tightly.

Melania shook it loose. Perhaps they'd had a tiff on the plane from Riyadh.

After all, they're only human!
