We wouldn't be full up if the EU had addressed their migrant problem in the first place. They let unlimited numbers pour into their external borders and then didn't actually want them and turned a blind eye to them massing at Calais. From there they've done very little to prevent them crossing the Channel so we've ended up with tens of thousands this year already. We don't have unlimited funds to house these people.
Well from France's perspective if it halts the flow then it's responsible for them.
I agree every country has a limit in terms of expenditure for supporting people seeking to become a member of the country. Low GDP countries are often the most corrupt and with the largest gap between rich ruling and poor surviving. So how do you solve that? If you provide aid then ethically you're doing the right thing but reality is that simply allows the rich to spend less and leave more to the aid (if they're not already syphoning aid payments).
Corruption enables corruption. People see it as the natural way to live. Unfortunately the majority of the planet isn't a self-entitled fair balanced democracy.
So unless you change the country, then you'll always have that problem. Russia is simply seeding the equivalent of US influence.
Russia and China's weakness is it needs strict control, it needs a strict morality to control with minimal force. It needs passive workers with tightly controlled bright academics to think outside the box but not outside the system.
Size of the nation from the central point of control becomes unsustainable. There is a difference between the Roman Empire (needing to hybridise Roman and local beliefs to control etc) and modern internet based & AI monitor and control. The modern world allows, through digital infrastructure, the monitoring & compliance to expand the range of compliance and influence but it still takes time to remove the local beliefs and traditions.
I would expect Putin to raise Ukraine to the ground, both as a reflection of force but also to attempt to fast erase the local beliefs and traditions in favour of the centralised agenda without the need of Digital technology.
I believe that Putin's plan was to perform a German style fast blitzkrieg, running across all the buffer non-NATO countries. However the real state of the Russian army became apparent and he's now progressing in a war of attrition.
