Two things spring to mind here. The first is the EU, for all its good intentions as the peacekeeper in Europe, it has been very slow off the starting blocks to respond to the crisis in Ukraine. Actions speak louder than words, and self-interest amongst some member states have enfeebled the EU and weakened any attempt at a concerted effort. Thankfully there now seems to be a united front amongst the 27 nations.
The second thing is that love of one's country has been sneered at and gradually held to ridicule by luvvies and lefties as though it is something to be ashamed of. Why do they disparage their own country when it should be valued and cherished? Now with Ukraine, we see love of one's country, one's land, one's freedom, in all its glory, as something precious and not to be given up lightly - something which is worth fighting for.
