呢段係我認真最大機取消到birthright citizenship既
birthright citizenship obviously doesn't apply in case of war or invasion. No one to my knowledge has ever argued that the children of invading aliens are entitled to birthright citizenship. And I can't imagine what the legal argument for that would be. It's like the debate over unlawful combatants after 9/11. Everyone agrees that birthright citizenship doesn't apply to the children of lawful combatants. And it's hard to see anyone arguing that unlawful combatants should be treated more favorably than lawful combatants.
