Balancing act is exactly the word I had in mind
OK, if the context is the Danish military then I think fighter jets do have their place especially when subcontracting to alliance ops. An all army Danish military doesn't can't maintain the same manpower levels as a balanced one.
And there are scenarios which pertains to Denmark, where a small fighter for is needed for sovereignty reasons.
I've only suggested using nukes for cost-benefit reasons when I'm sarcastic - just not an acceptable solution.
If we take DK as an example of a small NATO country: The budget for buying new fighter airplanes (most likely F35), 40 billion DKr, is nearly twice the yearly total defense expenditures of around 22 billion Dkr. For comparison the less-than-best-in-world Danish healthcare system (a major political issue in this country) could, according to the responsible, be ramped up to the very best in world, with an investment of 100 billion DKr, money that we don't have.
DK together with No and Sw are the proud weltmeisters of giving foreign aid to developing countries; That bill is 14 billion Dkr.
The entire education budget (primary schools, youth education, higher education) is around 120-150 billion..
So 40 billion is a lot of money.
So far, what has the airforce used it's fighter assets for? The most sexy I can remember was dropping bombs on tallibans, helping the balts "showing the flag" in their airspace, and showing the flag when an antiquated russian bomber lost it's direction (or witts) and got too close to bornholm. Now, not being an air general, I am pretty sure that a F16 can accomplish these tasks. I add to this that allready now, deploying the 6-7 F16s standing ready for rapid deployment to f.ex. Afgh, is so expensive that the defense hardly got the money and the allience demand for fighter aircrafts are near nill, since the allience got plenty of fighter aircrafts for the task at hand. It is my impression that the danish contribution to nato "fighter air tasks" are quite moderate or, rather, insignificant.
Where Denmark has been able to contribute significantly is in navial deployments, lately in Lebannon and anti piracy at the horn of africa. And ofcourse with a- relative to size, and many other NATO countries - disporportional army engagement in Afghanistan, where a lot of soldiers have been lost and billions of good money fired at "the enemy".
These policies of engagement has earned Denmark a lot of credit, and some influence, amoung our major security partners (noticably US/UK) on whom our national security fundamentally rest upon, and as such the danish defense has proven that it is relevant in danish security and foreign policy. But it's not the fighting wing of the airforce that doing the job. If US/UK wants some airpower, they deploy a carrier that has more airplanes than the entire danish airforce, but having denmark sending, say 1000, ground troops is partly 1000 US/UK families that doesn't need to miss their "loved ones", but more importantly it's a strong political signal to send infanteri into harms way, deploying air assets is more a question of "money", and it won't give DK the same credit.
So from a "do what you are best at" or cost benefit analysis, I think it's pretty sound to suggest that those 40 billion could be used a lot better on systems surporting the army (maybe some more air transports, helicopters or a full deployable brigade?) or on the navy, than a few hugely expensive fighters, that will probably only be used for fancy formation flying on the Queen's Birthday. Ofcourse then our old f16s has to soldier on, and should we feel threathed at some point in the future, a land based air defense system could be aquired, if needed (which is also consistent with the obvious future scenario: Robots will dominate the sky).
I stress that for a large country, the above doesn't apply.

I am not sarcastic. There is absolutely no reason to f.ex. pretend that we are willing to sacrifice so and so many 10000s of young men to stop country X from running over Taiwan, instead we suggest a diplomatic solution, if ignored, the tactical nukes are used, and if ignored, it's nuclear holocaust. Then country X won't begin in the first place.
