Under the 1951 Refugee Convention, non-refoulement is a near-absolute protection for refugees, but it contains explicit exceptions: a refugee can be returned if they pose a serious threat to national security or have been convicted of a particularly serious crime.

You might think a country must always protect a refugee who fears for their life. But what if that refugee is also a terrorist? The rule seems ironclad—yet there are cracks.
