Here’s one technique that helps me - internal brainstorming. Don’t try to be serious about coming up with an idea - think about many random vaguely related possibilities, combine them, reevaluate, etc.
Have your mind be in a state of flux jumping from one thought to another but not succumb to the pressure of having the final solution as quickly as possible.

After a while several coherent options will crystallize. Then comes the decision paralysis - unfortunately I have no cure for that.

This is very common in the EU. The majority of news sites do it. I believe it’s technically legal because they aren’t under obligation to provide a free access at all

Arguing semantics is not arguing in good faith.

In this “purely theoretical” case, exhaustion plays a huge role. There would not be a lack of volunteers in the beginning, say in the first year of war. After a couple of years and no hope of victory, it’s not surprising some people could decide to give up.

Now, should they be forced into war anyway? Tragedy of the commons or some such philosophical dilemma…

Mandatory training - Yes
Mandatory service - No

In the event of a real defensive war, where your nation is invaded with the intent of conquest or subjugation, you will not have a lack of volunteers. You will have a lack of trained people.

It takes a couple of months to train a new recruit. Having everyone ready to go will help tremendously during the initial stages of war.

On the other hand, a permanent mandatory service is 1. A waste of money, 2. Open for exploitation by corrupt governments
