The funds the U.S. has so far provided to Kiev already exceed U.S. spending in the first five years in Afghanistan, Fox News reported.

The Biden administration last week announced another $400 million aid package to the Ukrainian Armed Forces.

The latest package was reportedly developed in consultation with Ukrainian officials. Heavy artillery, such as howitzers and high-mobility artillery missile systems (HIMARS), are among the expensive weapons Ukraine says it needs to target Russian hotspots of control and control behind the front lines.

The Pentagon has confirmed that the U.S. has provided $8 billion in security aid since the war began in February, but Washington has pledged to spend much more.

Earlier this year, Congress pledged to spend $54 billion on traditional foreign aid and military assistance. The funds will be largely split through traditional channels to support Ukraine, but will also go to support NATO countries and U.S. troops stationed in Europe.

The latest $40 billion package passed in May includes measures that could take years to implement, such as the purchase of an additional Patriot missile battery that could potentially be provided to an allied country such as Poland.

It remains unclear how much the U.S. will eventually spend in 2022, but according to information provided by ForeignAssistance.gov, the U.S. has already spent more on security assistance to Ukraine than it did in its first five years in Afghanistan.

By the end of 2006, the U.S. had spent more than $7.4 billion fighting the Taliban. By 2011, the cost of the 20-year war had peaked with $11.4 billion spent this year alone.

Biden and other Western leaders have pledged to continue supporting Ukraine "for as long as it takes."
