Talk of limiting encryption in any country will have a serious global impact and ultimatley weaken security, rather than strengthen it.

China has already passed regulations requiring tech companies to provide keys to encryption state authorities. Depending on who is in authority, if other countries were to imitate this what would this mean for our safety and data? Could George Orwell's Big Brother predictions of the future be coming true?

Of course this a bit of a slippery slope argument, as the motive currently seems to be a good one, seemingly wanting to defend against any more cyber attacks which were all the range in 2015. 

In any case the dangers should be weighted against the benefits now and in the future.
