Rep. Kevin McCarthy, R-Calif., joined “Sunday Morning Futures” from Poland, where he spoke with refugees fleeing the war in Ukraine, citing “atrocities” in the country and the “sheer strength of the Ukrainian people.”

President Biden was chastised by the GOP leader in an exclusive interview for acting “too slowly” in Ukraine.

“Perhaps [Russian President Vladimir] Putin would not have made the decision to enter Ukraine if Biden had sent one weaponry earlier,” McCarthy argued on Sunday. “Perhaps Putin would not have entered if Biden had said he would sanction before they entered.”

“However, now that the war has been started, other countries are willing to provide MiGs to Ukraine so that they can defend themselves in their own airspace,” he continued. “[Ukraine is] not asking for American men and women to fight, all they’re asking is to have the weapons to defend themselves from an aggressor that is going in and killing women and children, innocent individuals, and there really has to be consequences for Russia’s action.”

He went on to say that the US must “supply Ukraine with the weapons it requires to win this war.”

Despite growing concerns that Russia is about to launch a large offensive in Ukraine’s eastern Donbas region, the US and NATO pledged Thursday to increase support for Kyiv. However, officials have remained tight-lipped about the type of weaponry they will send Kyiv.

NATO has refused to send troops or weapons to Ukraine, or to impose a no-fly zone over the country, in order to avoid being drawn into a larger conflict with nuclear-armed Russia. Individual NATO countries, on the other hand, have provided Ukraine with weapons, as well as equipment and medical supplies.

“Rest assured, allies are providing a wide range of different weapons systems, both Soviet-era systems and modern equipment,” said NATO Secretary General Jens Stoltenberg, who declined to say which countries were ramping up supplies or what exactly they might send to Ukraine.

Since the invasion began in February, Washington has provided more than $1.7 billion in aid, with more than $2.4 billion since January 2021.

A White House spokesman did not immediately respond to a request for comment from Fox News.

The “sickening images and accounts coming out of Bucha and other parts of Ukraine” have strengthened the West’s resolve to punish Russia and increase support for Ukraine, according to Secretary of State Antony Blinken.

According to Blinken, the US is “looking across the board right now, not only at what we provided and continue to provide, but also whether there are additional systems that could make a difference.”

On Sunday, McCarthy emphasized that Ukraine required the weapons “ahead of time,” and that “this is a lesson we should learn in the long run.”

“Remember, the president said just threatening sanctions would stop Putin, and then once Putin entered Ukraine, the president said sanctions would take a long time to work,” he told Bartiromo.

Late last month, President Biden suggested that sanctions were not intended to deter Putin’s actions, and he now tells reporters that “sanctions never deter.”

“Deterrence, sir, did not work. What makes you believe Vladimir Putin will change course as a result of your actions today, “During a press conference at the NATO summit in Brussels, Belgium, Biden was asked a question by CBS reporter Christina Ruffini.

Biden’s comments follow weeks of messaging from key Biden administration officials, including Vice President Kamala Harris and Secretary of State Antony Blinken, who claimed that the sanctions imposed on Russia were intended to deter Putin’s actions.

Members of the European Union, such as Poland and Romania, which are neighbors to Ukraine, have taken in the most refugees. Over 2.4 million of the more than 4 million refugees who have fled Ukraine have entered Poland. While many have traveled onward throughout Europe, many refugees have stayed in Poland, which is offering free temporary accommodation, medical care, education and some social benefits.
