- Finland, Sweden to join NATO after ratification
- Biden promises more troops, weapons to Europe
- NATO agreed new force structure to deter Russia
- Madrid protesters call for more arms to Ukraine
US President Joe Biden pledged more American troops, warplanes and warships for Europe on Wednesday as NATO agreed the biggest strengthening of its deterrents since the Cold War in response to Russia's invasion of Ukraine.
Biden's commitment at the Madrid summit "to defend every inch of allied territory" came as the US-led military alliance also set in motion a new plan to reinforce the Baltic states and Poland against any future Russian attack.
With more German, British and other allied troops to be on alert to deploy eastward, the United States is also adding to the 100,000 personnel already in Europe by sending more warships to Spain, planes to Britain, pre-positioned weapons to the Baltics and more soldiers to Romania.
"We mean it when we say an attack against one is an attack against all," Biden said.
However, Italian Prime Minister Mario Draghi played down a threat of a near-term armed confrontation between NATO and Russia. "There is no risk of a military escalation. We must be ready, but there is no risk," he said.
The Baltics originally sought permanent NATO bases and as much as a tenfold increase to NATO's troop presence from around 5,000 multinational soldiers prior to the Ukraine invasion, as well as adding air and maritime defences.
What NATO agreed on Wednesday falls short of that, but it means more allied troops in Estonia, Latvia and Lithuania, more equipment, weapons and ammunition sent to the region, and setting up a system of rapid reinforcements.
NATO leaders agreed to move towards putting more than 300,000 troops at higher readiness.
In the past, the alliance relied on far fewer troops - some 40,000 - to be first in line to respond to any Russian attack or other crises.
"President (Vladimir) Putin's war against Ukraine has shattered peace in Europe and has created the biggest security crisis in Europe since the Second World War," NATO Secretary-General Jens Stoltenberg told a news conference. "NATO has responded with strength and unity."
The United States will also create a new permanent army headquarters in Poland, which was immediately welcomed by Polish president Andrzej Duda, as Warsaw long sought a permanent US military base on its soil. "It is a fact that strengthens our safety a lot ... in the difficult situation which we are in," Duda said.
As NATO also agreed a long-term military and financial aid package for Ukraine, Ukrainian refugees gathered in central Madrid to call for more arms for their nation, which is now facing a war of attrition against superior Russian artillery in the east of the country.
Ukrainian student Kateryna Darchyk, 20, told Reuters: "We ask for NATO to give us weapons because we have soldiers, we have people ready to fight for Ukraine, men and women who are ready to protect their country."
END OF NORDIC NEUTRALITY
In addition, NATO's 30 leaders invited Finland and Sweden into the alliance, a decision that once ratified would end decades of Nordic neutrality by putting the two countries under the United States' nuclear umbrella.
"The significance of this really can't be overstated," Britain's Prime Minister Boris Johnson told reporters. "We're seeing the expansion of the alliance, which is exactly the opposite of what Putin wanted. He wanted less NATO, he's getting more."
That was made possible after Turkey dropped its veto against the two countries' progress to the membership following four hours of talks on Tuesday evening in Madrid, ending weeks of drama that threatened allied unity.
As part of the deal, Sweden and Finland agreed not to support Kurdish militant groups.
Turkish President Tayyip Erdogan had threatened to block their bids over Ankara's accusations the two countries supported a Kurdish militia in northern Syria. Turkey views the militia as an extension of the outlawed Kurdistan Workers Party (PKK) which is also deemed a terrorist group by the United States and the European Union.
Both Finland, which has a 1,300 km (810 mile) border with Russia, and Sweden, home of the founder of the Nobel Peace Prize, are now set to bring well-trained militaries into the alliance, possibly giving NATO Baltic Sea superiority.
"We are not yet covered by NATO's Article 5," Finland's Foreign Minister Pekka Haavisto told Reuters, referring to NATO's collective defence clause. "Our aim is that period should be as short as possible," he said.
