Yes, providing these weapons is costing the US a great deal of treasure - but no blood so far. We need to consider what we get back in return. First, stopping Russian aggression. Very hard to put a price on that, but I hear senior strategists say "priceless". And then there is the value of seeing how these advanced weapons behave in real battle theaters, and also seeing how the enemy responds. Again, it's hard to put a price on that knowledge.
