Ah, yes there is: the expense of the children with severed limbs dying every single minute under the rubble that was placed upon them by the very F35's you worship.
If it was "efficient" and "cost effective" to use the F35 to murder tens of thousands, its even more efficient and cost effective - and urgent - to de-weaponize them and use them to drop cluster medical kits.

We paint the F35's pink to make amends for the murder they have caused.
