if you add up all the defense budgets of the EU27 it is around 190B, only less then US and China. France and Germany spend around the same as the UK. And as you might be living in the past, the UK’s military is not exactly the might it used to be in the early 1900’s
The 190B figure is complete 'whataboutery' - NATO defence spending is measured in % of GDP, as you later note. If Germany is a paragon of military expenditure, why is their military currently a laughing stock (other than having had VDL as Defence Minister perhaps.....).
