Yes. Because you're committing an error in logic and tactics.
If I had these weapons, and was in their shoes, I would not use them. At least as the opening salvo.
What if they waited until US forces were on the ground?
What if they waited to use them in a counter attack, not necessarily against us, but some other nation in a design to further destabilize the situation. Say... India, for example.
There are other tactical considerations than merely opening up with your best shot...
