With Sweden now in, us Euros need a wake-up call to INCREASE SPENDING NOW 📈📈📈💪

Are the budgets calculated the same way in all countries? Or at least comparable?

I've heard that e.g. in Germany pensions for soldiers are not calculated as defence spending, because it's just a regular pension, the same civilians also get. However in the US the department of defense is directly responsible for that so it counts as defense spending. However I have no idea if that is true or if that is already considered in the 2% figure.
