The United States and its allies are preparing for a protracted conflict in Ukraine, increasing military aid to Kiev while trying to ease the consequences of the crisis in the form of possible world hunger and economic problems, writes The Washington Post .

According to the publication, this is evidenced by the announcement of US President Joe Biden to provide Ukraine with $1 billion, the largest tranche of US aid to date.

European countries, including Germany and Slovakia, also provided their weapons, including helicopters and multiple rocket launchers.

The decision to supply Ukraine with increasingly sophisticated weaponry, including anti-ship missiles and long-range artillery capable of destroying large military installations, reflects a growing willingness on the part of Western countries to risk an inadvertent escalation with Russia, the paper said.

Earlier it was reported that the US Attorney General will visit Europe to negotiate assistance to Ukraine.
