who is gonna be bombing us? seriously. No country on earth has anything close to the technology to seriously challenge the USAF. Iran? North Korea?
Iran. Surface to surface missile launched from a ship off the east coast of the US. EMP or nuke. Pakistan has multiple subs with 12 nuke capable launch tubes. China has been selling nukes and missiles to Iran. Any technology that we wish to field for the military takes 10 to 20 years from concept to deployment. When you cut the defense funding, the people who are capable of doing the work have to find another line of work. Often you can’t get them back when someone finds money again. The technology is lost and costs more to recover if it can be recovered at all. Our enemies steal our technology. Clinton handed the Chinese ring gyro technology in exchange for campaign cash. That enabled them to put rockets into space and nukes on US soil. Toshiba compromised the propeller milling technology that makes our subs quiet. Now those Paki subs are less likely to be detected.
