A new Supreme Court decision on birthright citizenship is framed as a dangerous loophole that could be exploited by foreign spies.

• The Court ruled on birthright citizenship, and the worry is that it opens a national security gap.
• The fear: a foreign agent, such as a Chinese spy, could have a child on U.S. soil and create an instant future citizen.
• That child could be raised abroad, taught to serve another country, then return to the U.S. for school or work.
• This is called a loophole the founding fathers never intended, in the same spirit as anger at the earlier Citizens United ruling on election money.
• Citizens United is blamed for letting big money flood elections and crushing independent candidates who lack party or PAC backing.

Outlook: Expect continued political fights over whether birthright citizenship should be narrowed to close this perceived gap.
