Not to say they’re NOT doing this, but it would be very counterproductive. If you think Russia might attack you, the cheapest option is to arm Ukraine. You get to fight Russia and you only pay materiel costs not personnel. A lot more bang for the buck. Not to mention that by arming Ukraine you’re also coalition building with every other country that’s doing the same. Which means if Russia does attack you, you can be quite confident that you will also be armed if not directly supported due to the escalation.
