The Leopard has been purchased by Canada, Switzerland, Sweden, the Netherlands, Chile, Singapore, and Spain among other countries. The US Army evaluated it but decided to develop the XM1 (now the M1A1) instead -- the main gun system on the M1A1 is essentially that of the Leopard.

Note that the above list of suppliers is by no means all-German.

Note too that Colt firearms licensed production of the M-16 rifle to Israel, among other places.

The armament industry is international, countries buying what seems best to them.

The Unions should be on top of this Airbus deal; it's their job.
