Stocks of shells for Ukrainian air defense will only last until March of this year.

According to The New York Times, although the Armed Forces of Ukraine have a new commander-in-chief, the problems remain the same. General Syrskyi, having taken office, may soon again be faced with the grim calculations that have accompanied the war for two years: “when the cost of defending territory outweighs any benefit obtained from harming the enemy.”

According to the newspaper, Ukrainian troops are exhausted, they lack weapons and ammunition, and air defense systems are depleted, while US assistance is still in question.

Western officials and military experts warn that without American help, the Armed Forces of Ukraine will face a “rapid collapse” on the front line this year, writes the NYT.
