If 55% or more of the business comes from ME customers it only makes sense to headquarter there to be close to and be able to service customers as quickly as other competitors.

If most of the earnings are generated in the ME they probably should think about giving back to the communities providing the jobs and not the USA whose only function appears to be providing mgmt and possible technical people and taking 35+ % of the profit in taxes.

Halliburton is not a 'make work' company, it's 'job' is to generate a return to the investors by providing services the customers are willing to buy & pay for.

If the USA restricts US based companies or artificially reduces or limits their ability to make a profit it would be easier for me to invest overseas directly bypassing US companies or actually physically relocating outside of the US to avoid some or all US taxes. ie Dubai is income tax free for both companies and individuals.

Capital funds will always flow to areas of best risk/reward. Any country with high risk or attempts to restrict the flow of capital will lose jobs, companies and living standard. ie Ask Zimbabwe

The UK Telegraph wrote about Dubai advantages for companies and employees.
