Whether it's a good thing or not depends entirely on your philosophical views. There is no objectively correct answer, and which arguments may convince someone very much depends on the values and perspectives of the person you are trying to convince.
What kind of resources are we talking about here? Clearly it doesn't help to make you talk to 1 person that holds contrasting views, as that seems to be your starting point. A study of 1000? A study of 100000? An empirical research over 100 years? 500? A meta analysis? 5 people talking to you about it? 10? 100?
We don't have a way to do this. I don't think we ever will. Wish the answer was different.
The one thing I will say is that logical argument is extremely ineffective for changing people's views. Personal, emotional stories are best. The issue is that war and the draft is already highly emotionally charged, so it's gonna be hard to find something that will strike a nerve with someone who hasn't already come around on it.
Classically, you'd discuss their views with them and find the logical conclusions. Then you'd talk though if those ideas contradict with other ideas they hold. That sort of discussion/dialogue is basically all of Plato.
First you set up a news agency. You tune into their fear of inadequacy. You craft stories and spin truths to Make sure that they're good and scared of the future of them and their family. You keep slowly chipping away until they have no problem with suspension of disbelief. You make sure that day and their friends all have the right tools to indoctrinate each other. Then you get small and big business on board by offering them tons of money to help keep everybody good and scared. You craft laws and put people in the right places in police organizations to make sure that the people you're trying to scare them with are seen as the Boogeyman. Sure, it's not technically forcing but it's forcing...
