WASHINGTON — President Joe Biden welcomed NATO leaders to Washington on Tuesday by celebrating their unity against Russia's Ukraine aggression and underscoring America's ironclad commitment to the alliance under his watch — a message that seemed aimed at bucking up his own wobbly Democratic supporters as much as allies confronting the prospect of a return to the White House of NATO skeptic Donald Trump.
Biden has been straining to persuade U.S. voters and donors that he's ready for reelection after a stumbling debate performance against Trump. He's been making his case on the campaign trail, in a defiant letter to Democratic lawmakers and now at an international summit that he's still up for four more grinding years in the White House.
''Today, NATO is more powerful than ever—32 nations strong, Biden said as he welcomed leaders at an evening event to mark the 75th anniversary of the alliance. ''It's good we're stronger than ever because this moment in history calls for our collective strength," he declared head up and voice strong.
The summit comes at trying moment for Biden's presidency. Several Democratic House members have publicly called on him to quit his campaign. Other lawmakers in private conversations have urged him to step aside, and several high-profile donors have raised concerns about his viability in the race against Trump.
Biden has no shortage of difficult substantive conversations ahead about global security over the course of the three-day NATO summit. But the White House is also looking to display to America that he has the stamina for crowded days and evenings of formal meetings, sideline chats with world leaders, long diplomatic dinners and receptions, and a summit-ending press conference.
Biden on Tuesday announced major steps the U.S. and other NATO countries are taking to beef up Ukraine's overwhelmed air defenses. The U.S., Germany, and Romania are donating additional Patriot batteries, while the Netherlands and other allies will donate additional components to operate a Patriot battery. Italy announced last month it is sending an SAMP/T defense system to help Ukraine.
Other allies, including Canada, Norway, Spain and the United Kingdom will provide other systems aimed at improving Ukraine's defenses.
''This is a pivotal moment for Europe and the transatlantic community, and I might add to the world,'' Biden declared.
