It is just for domestic purposes, the American presidency has no clue of what they are doing and are just trying to appease to the people that voted for them.

Instead of trying to better their country by means of funding NASA, the National Science Foundation or in education as a whole I think they are wasting their money on more war machinery that it is not actually needed.

I think it goes deeper than that, by augmenting the funds on "defense" they are effectively making the rich, richer they are favoring to the high social class of the USA since most of them build tanks and weapons. Like the Bush family, they are just spending for the sake of their buddies.

Thank you for posting this reflection and analysis.
