Is US $800 billion weapons program sustainable?

 Is US $800 billion weapons program/expenditure sustainable?

It is increasingly becoming expensive to have the biggest war arsenal in the world.  To be the defenders or democracy in the world.  

Weapoons equippped with high tech are becoming more expensive to build.   A Gerald Ford class aircraft carrier costs $13 billion to build (taking five years)  An F35 will set you back by $100 ++ excluding the sustainment (maintenance cost)  That isi too much burden for taxpayers to sustain.   With staggering  $35 trillion in debt, there will be taxpayers revolvt.

Elsewhere in the world, the Hamas and Houthi have shown that they can manufacture cheap rockets that can overwhelm the more expensive Iron Dome or Patriot Air defense system.    See how the cheap Russian drones are wrecking havoc on the  multi million dollar Abrams tanks.  And how the cheap shoulder launched weapons from Ukrained are destroying expensive Russian aircraft.

Very soon US taxpayers will search for cheaper weapons that 1.  survival,  2 are not vulnerable, 3.  will not cause death of US military.  (are survivable)
