The Biden administration is reportedly working with Poland on a new deal that would provide Ukraine with fighter jets. The planned supply of Polish fighter jets comes amid growing pressure from Ukraine on the west to help support its ability to repel Russian aerial attacks.

Under the proposed deal, Ukraine would be getting Russian-made jets from Poland, while Poland would receive F-16s fighter jets from the United States. Given the poor development of elements of Russia's ground operations, there are worries that air attacks may be increased in the coming days.

The White House said it was in talks with Poland and discussing the plan with other NATO partners, but that there were a number of issues that needed to be solved first, such as how they would transport the planes from Poland to Ukraine.

U.S. Secretary of State Antony Blinken said Sunday that the U.S. is now actively looking for ways to deliver military aircraft to Poland if it decides to send its own to Ukraine. He added that he still doesn't have an exact timeline of when deliveries can be made, but they are looking at it "very, very actively."

Polish officials previously stated that they were not in any way in conflict with Russia, but it also cannot remain as an impartial country. Officials said, ultimately, any military decision regarding Ukraine must be made by NATO as a whole.

Ukrainian president Volodymyr Zelensky had requested for the U.S. to help it acquire fighter jets from its eastern European allies. Zelensky has also been calling on NATO to institute a no-fly zone over Ukraine. If this was not possible, he requested that NATO support the nation's ability to protect its skies. He added that they needed Russian-made planes and not F-16s as Ukrainian pilots were trained to fly Russian planes.

Ukraine has received a variety of weaponry from the United States and its allies. However, concerns still remain that President Vladimir Putin would see the deployment of airplanes and weapons as an escalation, which he might perceive as NATO joining the war. Putin stated on Saturday that any third-party establishment of a no-fly zone would be considered an engagement in the armed confrontation.

Sending planes, according to Polish President Andrzej Duda, would be equal to intervening in the war. On Sunday, Russia's defense ministry cautioned nations bordering Ukraine against allowing Kyiv's air force to use their airbases and said Russia will now target defense sector installations in Ukraine with air attacks.

Over the past few days, the U.S. has been stepping up its support for Ukraine by sending anti-aircraft stinger missiles, the same weaponry that the Mujahedeen used to oppose the Russian invasion of Afghanistan. U.S. President Joe Biden talked with Zelensky on Saturday evening and reportedly told him that the United States will be expanding security, humanitarian, and economic support to Ukraine and that the U.S. is working closely with Congress to gain additional funding.
