But re-arming ourselves costs money?

And we have to share the bill, because from a sovereignty aspect, we can’t defend ourselves alone.

I think the question is, how to split the bill fairly. Per citizen? But some countries are better off than others. Is it then fair to raise the bill to a level where it damages some countries’ healthcare, social care, schools, care for the elderly?

How does defending our countries limit democracy?

We have to stand together and have the military to uphold sovereignty otherwise there is no democracy.
