That is the problem with these "Diaspora" politics, and listening to anyone who hate itself and his own people, they are always going to be bias, make misleading arguments and most cases outright lie. You have to take what they said with a truck load of salt.
Look the Iranians. Their diaspora along with the Israelis mislead the US into their most disastrous war since Korea. Instead of regime change they will get a stronger Islamic Republic, probably with nuclear weapons and at best a global economic crisis, at worse a global economic depression.
This people could lead the EU in a energy depression, high inflation, scarcity of manufacturing supplies <a lot of them comes from China> and a TWO FRONT trade war against China and the Trump US who is going to use a EU-China trade to gain leverage in his trade war against Europe.
