UK is up for grabs.
The Church of England will no longer exists. The King - defender of the faith - will have to convert to Islam & the great UK parliamentary members equally will have to convert to being muslims, or else:-
a. The new citizens & migrants will not vote for them, & will THREATEN others whom do not vote as they do, either by guile or by violence.
b. As a Force, even though a minority, they will shut down Parliament, force the British cabinet to sack any member whom does not do as they want.
c. If that does not work, they will stage strikes upon the economy - transports, biz enterprises, etc.
d. Once they gain power, they will welcome more migrants from muslim nations, take over Parliament & seize the English throne to be replaced with a Caliph as leader of the Supreme Council.
e. The military - navy, land, air forces personnel will have to convert to Islam, grow beards or will be sacked & replaced by new migrants.
This is the playbook, observed by how Persia Shia Iran conquered/stole lands from natives. As UK is facing economic difficulties, with many natives having financial issues, it is the best time to seize power.
Equally so, so too is France up for grabs. Seems only Hungary Victor Orban was wise.
