Some time ago the federal government was trying to legally obtain the power to strip and American citizen of their citizenship. At the time it seemed obvious that the reason the politicians in Washington DC were going for that power was to give Obama a means of getting around his promise not to indefinably detain American citizens under the National Defense Authorization Act (NDAA). The United Kingdom may just demonstrated another benefit of stripping citizenship, the government can blow a former citizen up with a drone and claim they haven’t killed any citizens:
The Government has secretly ramped up a controversial programme that strips people of their British citizenship on national security grounds – with two of the men subsequently killed by American drone attacks.
Governmental protections are more mythological than unicorns. Any supposed legal protection put into place is easily bypassed with the stroke of a pen.
