“Citizens want them to act now, and not in 30 years, he said.”
By 2050 (30 years from now) most of Western and Central Europe will be under Islamic rule (just due to demographics, even if immigration were to stop), and I seriously doubt that the new leaders there will give a crap about playing along with this hoax.
Or (as I long predicted along with predicting the Muslim invasion) Europe will have yet another bloody purge of non assimilated enclaves, break apart again into smaller countries all of which will be fiercely nationalistic.
Because this pattern has repeated cyclically for thousands of years.
