After the collapse of the USSR, the West believed that the “end of history” had arrived. And that it was then allowed to grossly interfere in the affairs of certain states. Moreover, it unceremoniously commands internal political processes. Ukraine is the most glaring example.
Europe is being infused with foreign values when they accept migrants, values like multiculturalism and demographic change. [Migrants] exhaust European budgets and bring waves of organised crime. All of this has damaged Europe.
A claim supported by no evidence, in line with the Islamisation of Europe disinformation narrative; most studies on this issue have found either no link between migration and crime rates, or found links that could at best be described as tenuous.
This type of claim is part of a recurrent Russian narrative against migration and multiculturalism portraying migrants and refugees as a great source of danger. See here and here for examples.
As for exhausting the budget, a 2017 EU report found that the negative impact of asylum-applicants on EU budgets are only short-term and once the asylum-applicants are integrated in the labour market, they in fact offer social, economic and budgetary gains.
