Throughout Europe and North America immigration is under discussion, be it Mexicans crossing the border illegally into the US, immigration 'amnesties' or the fears that Britain and other Western European nations will be flooded with people looking for work from the Eastern European countries about to be absorbed into the European Union and thus allowed free movement across former borders.
The debate, as usual, and by design, has been polarised into a Left-Right slanging match. If you challenge the level of immigration you are branded a racist, for example. But this is not about what is good or otherwise for a country or the immigrants themselves.
This appears to be a long-term plan to destroy the nation state. Whether people support the nation state structure or not is another debate.
The nation state structure, and the history, culture and sense of uniqueness that goes with it, are road blocks to the absorption of nations into a single centralised world state, under the same government, army and economic system.
To break down resistance to this global state, the sense of unique national identity and culture would first need to be destroyed. The concept of 'nation' would eventually be lost throught the creation of 'multicultural' societies. That does not necessarily mean that 'multicultural' societies are wrong - not at all - only that there is an another parallel agenda.
The expansion of the European Union is, in part, designed to do this.
The danger is that a single governing body could potentially be granted dictatorial powers on the pretext of world peace and global equality. This would threaten freedom and personal liberties.
