It would be a shame if oine day we had to fight these tanks, and it is well within the realm of possibility.
We have given weapons to others before only to have them used against us.
5 countries [US/RS/CH/UK/FR] make 70 percent of the words military weapons. 85 percent of the aircraft. Exports are how they support the industry for their military force.
The exports are ussually less capable than used domestically. E.G. the lack of DU armor on export M1A1s is the equivalent of 2 inches less of steel armor.
And certain systems are not exported. Everything we are SELLING to Iraq is 1970/1980s tech. What we are donating is 1960s/1970s equipment that we are eliminating from our inventory.
