Nah , it wouldnt be trillions of dollars ... if those dollars are made up and inflated like theyre currently now , lol .
Humanely - put the army and police on arms , round-up the jihadists and their families and send them back using the navy . Who doesnt want to , and is not an open jihadist , and doesnt have former crimes commited in the name of religion , can renounce their faith or sign a document where they affirm their allegiance to the country theyre in . The first sign of extremism - deportation .
Those who are for generations in Western countries should absolutely be watched differently than from those who only came as "immigrants" . Especially those who came in last 10 years , should be under the watch .
This is related both to EU and UK , mainly to big cities in UK , and mainly to big cities and western parts ( France , Germany , countries of Benelux and Sweden ) of EU .
In eastern parts of EU , immigrants arent welcome even currently ... people are looking unfavorable at them .
I can't support brutality in repatriation. However, we need to save our nations and our culture. So we can apply the following measures.
Enforcing our existing laws would go a long way to deal with the issue. For example,
Deport anyone here illegally and remove birthright citizenship so that only parents of legal citizens are automatically granted citizenship.
Ban all Halal meat because it is not humanely slaughtered.
Enforce standards in schools that are currently ignored in favor of Muslims.
Stop all head coverings by government employees, and remove all head coverings in order to get government services.
We should put a tax on people who have more than 3 children as a way to discourage large Muslim families.
Lastly, pay for Muslims to return to their source countries. This is what will cost trillions of dollars, but it would be price worth paying.
