If Drumpf said we were paying more than our fair share of military defense. We clearly have some fat to cut and even some meat and still be ahead. By then NATO will be paying their fair share and it will balance out any deficit. Such as single payer healthcare. Infrastructure contracts to legit American companies. With a legit American supply chain. Free education in facilities that are state of the art education for the new economy. Stop about 90% of the corporate welfare. 
Instead, use the cash for the common welfare of the people. Not for decades long proxy wars. Then pay to rebuild the destroyed infrastructure in the country we destroyed.

It's not rocket science.
