American superior weapons technology, used by the Ukrainian military to very good effect against Russian soldiers and equipment, no longer work so well.

 …the M982 Excalibur munitions, developed by RTX and BAE Systems, became essentially useless and are no longer employed….

And

 Russian electronic countermeasures have significantly reduced the precision of GPS-guided missiles fired by Himars systems….

And

 …the Ground-Launched Small Diameter Bomb munition, manufactured by Boeing and Sweden’s Saab, has failed altogether after its introduction in recent months….

Yet,

 Some of the other Western precision weapons, provided more recently, continue to strike high-value Russian targets.

But that won’t last. It’s an old an hoary maxim in the military that the enemy gets a vote, too, on the battlefield. Adaptation to the other side’s weapons is just one of those votes, and it’s just a real-time battlefield instance of the overall arms race between adversary nations.

Of course Russia is adapting in the particular case.

This is just one more foreseeable consequence of the terrible immorality of Biden’s slow-walking and outright blocking of the weapons Ukraine needed, and needs, to win its war of survival outright, and to do so quickly. Russia—sanctuary Russia in Biden’s foreign policy—was donated time to adapt to the weapons and to find and deploy counters to them.

Aside from Biden’s bloody immorality, this also is one more reason we need to step up our pace of innovation and vastly increase our ability rapidly to produce what we innovate.
