Ukrainian forces are already rationing ammunition due to the delay in the US aid, and the cessation of US support will be crucial for Ukraine — CNN.

Senior US and Ukrainian officials have reported that Russian forces now have a five- to sevenfold advantage in shells over the Ukrainian Armed Forces. This leads to additional losses in the ranks of the Ukrainian army.

According to Western officials, without additional US assistance, Ukraine would first run out of long-range missiles, then air defense missiles, and later artillery ammunition and short-range missiles such as shoulder-fired Javelin anti-tank missiles and Stinger anti-aircraft missiles.

"Each category of munition has been crucial to Ukraine’s defense. The long-range missiles, such as the UK-supplied Storm Shadow cruise missiles, have been central to Ukraine’s success in pushing back Russia’s Black Sea fleet hundreds of miles to open up a shipping corridor for grain and other supplies.

Air defense missiles have proven particularly essential in recent weeks as Russia has expanded its attacks on civilian infrastructure this winter.

Shorter-range missiles have enabled Ukrainian forces to defend against Russian tanks and aircraft, which greatly outnumber their own," the article says.

A senior US military official believes that without US and NATO assistance, Ukraine will last only a few months in this war and will be defeated in the summer of 2024, CNN reports.

In Europe, there is also increasing discontent with the actions of the US Congress, which is blocking aid to Ukraine.

“I don’t think people fully realize what Ukraine’s fall would actually mean. We would see horrible things: ethnic cleansing and the total destruction of Ukraine. Remember what they did in Bucha. If we can prevent this, it will be a success,” an unnamed European diplomat stated.
