There are very numerous factual errors/half-errors in this article (troops, planes, Budapest Memorandum, etc.).

The key point to address is: Will these long range missiles (that Ukraine has been using inside Ukraine for a while) have a chance to change the outcome of the war? The answer is, "No."

The US has delivered probably fewer than 50 ATACMS to Ukraine. We don't have more to give because the US produces very few, we need some ourselves and we share with other allies.

Ukraine fired 6 of 50 and had 1 hit. Extrapolating from that we can expect that Ukraine will hit another 7 targets inside Russia.

"From September 28, 2022, to September 1, 2024, Russia launched a total of 11,466 missiles. On average, 23.2 missiles were launched daily, with the median number of daily launches recorded at 17 missiles."

Meaning Ukraine has enough ATACMS to match Russia's missile firepower for 2 days. Yes, this is a bit of an "apples to oranges" comparison, but assuming that Russia hits as often as Ukraine is VERY generous for Ukraine, so maybe it gets us back to the same fruits.

Russia is outproducing the entire West (plus Pakistan) in weapons production. They are bringing in 30,000 recruits (not conscripts) PER MONTH.

The best this escalation by Biden can achieve is that Ukraine does not collapse before Trump takes office and so that after Ukraine loses the Biden administration can claim they did everything they could to stop Russia.

What it means in practice is that negotiations are being pushed off. More Ukrainians will die needlessly. More Ukrainian land will be lost. Ukraine will pay the price for this escalation without gaining anything in return.
