RSA-based encryption may be insecure right now; I strongly doubt any agency has access to a quantum computer powerful enough to break it. But if it is insecure, it doesn't really matter. The US can't do anything with the information it gains, because the US can't let anyone know they can break RSA-based crypto. Once it becomes known that powerful enough quantum computers are around, the entire crypto community will switch to one of the several algorithms that are immune to quantum attacks, so their capability is really only useful for a one-time thing. If I was a major criminal organization I might have already invested time to switch algorithms.
