We're all under threat. I'll grant you we're vulnerable with 25 million people and 8 million square million kilometres with powerful neighbours - China 1.4 billion, India 1.39 billion, Indonesia 280 million, Japan 125 million, Phillppines 113 million, and so on.
We're off topic anyway - it was about terrorist cells within nations, not the mililtary threats between nations.
But I'll quote you my old pastor again. He remarked "I think we (Anglo-Saxons / Europeans / present Australian population) have been put here in a 'caretaker' role between the original indigenous civilisation and the next one" (whatever it will be - I've got my own thoughts on that).
There are already far more Asians here than there were when I was a kid when we still had the "White Australia" policy. When i was young it was rare to see Asian faces - there was the occasional Chinese but not much else.
Now Asians are everywhere, along with Africans, South Sea Islanders and some South Americans.
Of the top ten nations for immigration in 2021-22 seven were Asian. Only the UK, NZ, and South Africa were not. I don't know if the South African contingent were mostly European or African. There are quite a lot of Middle Easterners. One thing is clear - the 'caretaker' role of what might be called the Anglo-Saxon race is being challenged. And if we are invaded by another nation, it's unfortunate but I doubt if our indigenous population will fare any better than they have under us. I think they'd do a great deal worse but that's just my opinion.
The top 10 countries providing the most permanent migrants to Australia in order of rank for 2021–22 are:
- India
- People’s Republic of China
- United Kingdom
- Philippines
- Nepal
- Vietnam
- New Zealand
- Hong Kong (SAR of the PRC)
- Pakistan
- South Africa
But I wouldn't be too smug about being in Europe. You're being challenged yourself by Moslem immigration and you still have a nuclear armed Russia over the border with a war going on at the borders of Eastern Europe. In an age of inter continental nuclear missiles none of us are immune.
The only real security will be the next life IF we get to heaven.
