 F-16, no silver bullet for Ukraine against Russia, NATO Secretary-General Jens Stoltenberg. F-16 fighter jets would not serve as a silver bullet for the Ukrainian armed forces amidst the ongoing conflict with Russia, cautioned NATO Secretary-General Jens Stoltenberg. The swift delivery of these fighter jets to Ukraine would serve as an example of significant military support for Ukraine from NATO, Stoltenberg said. NATO allies providing Ukraine with F-16 fighters, sending weapons for those planes, and training pilots is a very important example of the alliance's military assistance to Ukraine, he said. However, no single system can change the situation on the battlefield alone. F-16s are not a silver bullet that will determine the course of the war. F-16s are important for Ukraine as they will increase its capabilities on the battlefield, Stoltenberg said. He expressed appreciation for Ukraine's allies' dedicated efforts in facilitating these deliveries and providing training for pilots and technical personnel involved with the F-16s. UK Prime Minister Rishi Sunak announced that his country, along with the United States, the Netherlands, Belgium and Denmark, had agreed to participate in training Ukrainian pilots on Western fighter jets on May 19, 2023. Romanian officials said on July 6, 2023 they were opening a regional training center for F-16 fighter pilots, which would be available to its allies and partners, including Ukraine. According to media reports, the first F-16s will appear in Ukrainian skies around June 2024. The Belgian government recently approved the allocation of its 25th aid package for Ukraine, which includes funding for the maintenance of F-16 fighter jets. Denmark and the Netherlands were the first countries to pledge to send F-16 fighter jets to Ukraine but said this would happen after the Ukrainian pilots had completed their training. Vote on aid to Ukraine in US Congress may be postponed for several weeks. The House of Representatives vote on aid to Ukraine is unlikely to happen until at least mid-April and possibly later as Speaker Mike Johnson is still seeking ways to soften opposition from radical Republicans. Bloomberg reported this, citing the leader of the Republican Party in the House of Representatives. They say that Johnson's team has not shared a detailed plan regarding the aid package with Republican lawmakers, and it seems undecided on the actions he will insist on from President Joe Biden's administration, making it difficult for him to secure support in time for a vote next week. Johnson spokeswoman Taylor Halsey stated that the Speaker's promise of swift action did not intend to establish a specific deadline and that Johnson was sounding out members. Regarding the plan, she did not provide further information on the Speaker's consultations. Two representatives of the Republican leadership stated that there is still a possibility that Johnson could decide regarding the Ukraine aid plan over the weekend and expedite the project's approval next week. However, Bloomberg notes that such an accelerated schedule could lead to the bill's failure and further confrontation with hard-line supporters within the Republican Party. Recently, the administration of the US President refused to accede to the proposal of the Speaker of the House of Representatives Mike Johnson to provide aid to Ukraine if the President reverses his decision to suspend the issuance of new licenses for liquefied natural gas exports. The US Congress' approval of over US$60 billion in aid to Ukraine is currently being blocked by Republicans in the House of Representatives. The White House has repeatedly cautioned that this would significantly harm Ukraine's military efforts on the battlefield.
