Cut them all off. Do not accept goods from any socialist, Marxist, country. Do not give any money, loans to any socialist, Marxist country or allow money to be sent. And the biggest, bring all Military home and do not send them to defend any socialist, Marxist nation.
Then clean house at home. Door to door if necessary.
Within a month the world would change, these aspiring natzi nations would collapse. End Blackrock, Vanguard, Catholic charities, ADF etc.
No money cost, no bullying, no diplomacy, no excuses, no military loss of life. Let them follow by example, or cease to exist. Enough is enough.
