Ukraine President Zelensky gives historic address to US Congress

On Wednesday, Ukraine's president thanked "every American family" in an emotional (but defiant) address to the US Congress, aimed at countering growing scepticism over US military aid as Kyiv's conflict with Russia drags into the new year.

It was Volodymyr Zelensky's first overseas trip since the beginning of the conflict with Moscow on February 24 that upended the global economy and led to widespread destruction and death.

"On this special Christmastime, I want to thank you, all of you. I thank every American family which cherishes the warmth of its home and wishes the same warmth to other people," he told lawmakers who had given him a lengthy standing ovation as he walked into the House chamber.

The conflict has begun to recede from the headlines in the United States, with no end to the fighting in sight and Republicans — who take over the House of Representatives in January — showing signs of weakening resolve.

In what was billed by US media as the most important speech of Zelensky's career, he told a joint meeting of the House and Senate that his country would never surrender, adding:

"Ukraine is alive and kicking."

However, he urged lawmakers — many of whom were dressed in the blue and yellow of the Ukraine flag — to do more for his nation through the brutal winter months, pleading for more weapons and financial aid.

"We have artillery. Thank you. Is it enough? Honestly — not really," he said in a frank moment that pierced what had been an upbeat atmosphere, with his words accompanied by several outbursts of spontaneous applause.

He stressed, however, that US aid for Ukraine is "investment," not "charity".

Discussing his visit on Tuesday to the war's southeastern front line, Zelensky presented lawmakers with a Ukrainian battle flag signed by soldiers from the besieged city of Bakhmut.

The Washington visit — which came about 300 days after Russian hitmen parachuted into Kyiv in a failed attempt to assassinate Zelensky — underlined Ukraine's near-total reliance on Washington for its defence.

It coincided with President Joe Biden announcing a first Patriot missile defence system for Ukraine, which has been devastated by air strikes leading to widespread power outages as winter bites.

Zelensky thanked politicians from both parties, but his appearance was also calculated to counter fatigue for the war cause, particularly among isolationist Republicans who have voiced doubts over the continued flow of tax dollars to Kyiv.

Congress is poised to pass $45 billion in additional military and economic aid to Ukraine this week as part of its $1.7 trillion annual funding bill, bringing total US assistance to over $100 billion.
