This 5 December 2018 from Senator Bernie Sanders in the USA says about itself:
This Dutch post by the Amsterdam Peace Initiative says (translated):
NO to shell companies of tax dodging weapons producers
Wednesday 19 December 12am-2pm
Five of the largest arms corporations in the world (Lockheed Martin, Boeing, BAE Systems, General Dynamics and United Technologies) have an official office in Amsterdam. These are no more than shell companies, exclusively intended to avoid tax.
All these companies supply weapons to Saudi Arabia, which thus can wage the horrendous war in Yemen. Dutch companies are [officially] not allowed to supply arms to Saudi Arabia, but financially the Netherlands plays a role in the arms trade that keeps this war going.
The favourable tax climate in the Netherlands gives the international arms industry even greater profits.
All these companies are also involved in the development, production and maintenance of nuclear weapons, while Amsterdam has declared itself to be a nuclear-free municipality in the past. And they supply weapons to many more dubious customers: countries at war, with internal violence and human rights violators.
