That's a very difficult question. The NATO spending target is a spending target. It's not a target or a metric that assesses military readiness.
In questions that your colleagues asked prior to yours, they asked what a quick way would be to reach the 2% target that would still make sense. Mr. Housefather asked that question. A quick way that would not necessarily make sense would be to increase eligibility for veterans' pensions or significantly increase veterans' pensions. That would help with reaching 2% of GDP on defence, but it would not help in any way for military readiness.
I'm not the best person to assess what the best metric is for military readiness. For that question, you'll need somebody who's a specialist in military doctrine and military operations. Unfortunately, I cannot answer whether the 2% spending target by NATO is also something that would materially contribute to military readiness. It depends where the spending is directed.
