The Guardian reports.Tony Radakin, the head of the UK General Staff, will take part in a Pentagon meeting on Wednesday aimed at finalizing what 30 different countries are prepared to do to ensure Ukraine's security.Radakin is expected to confirm that the UK will provide troops to support logistics and training, but will not deploy them near Russia. Officials had discussed sending up to 30,000 personnel to protect Ukrainian assets, but that number has been reduced amid opposition from some European countries.“Wednesday is a really important moment. Nothing happens in Washington without the president giving the green light, so Trump giving his support to security guarantees on Monday kickstarted a lot of activity,” one British official said.Another official said Radakin will reiterate promises made last week by Defence Secretary John Healey, who stated that the UK is ready to deploy troops to Ukraine “to ensure safe skies, secure seas, and to strengthen the Ukrainian armed forces.”According to ministers, this refers to logistical and training support—not the deployment of battalions that could end up on the front lines or engaged in combat.Wednesday’s meetings are seen in Europe as a key step toward a peace agreement between Russia and Ukraine, which, according to Keir Starmer, will only be possible if the U.S. is willing to provide security guarantees.Wednesday’s scheduled meetings at the Pentagon are being closely watched for any signs that the U.S. is ready to make commitments. On Tuesday, Trump insisted there would be no deployment of American troops on the ground, telling Fox News: “You have my assurance [on that], and I’m president.”But the UK also plans to use these meetings to explain to the Trump administration what it is prepared to do to help protect Ukraine if a peace deal is signed. Officials say British troops could be deployed to assist with logistics in defending Ukraine’s airspace and ports, but not in situations that could lead to direct combat with Russia.Some experts say European leaders don’t expect Putin to accept even such limited NATO troop deployments in Ukraine, and that they are instead considering a strategy to isolate the Russian president.British officials insist this is not the case and that the UK and its partners are seriously preparing to send troops to Ukraine if needed.“You don’t get 30 chiefs of staff coming to the Pentagon if they are not serious about this,” said one.The European Union's chief diplomat, Kaja Kallas, stressed that only reliable security guarantees for Ukraine will deter Russia from a potential attack in the future.On Tuesday, August 19, leaders of the Coalition of the Resolute agreed to soon hold talks with the U.S. on "reliable security guarantees" for Ukraine.
