I will pray for you and your family to be successful in your intervention. Trust me your suspicions and beliefs are more facts than you think, if things have progressed this far to a planned intervention then you nephew is only short a MDs medical diagnosis in having alcoholism. I work with alcoholics weekly and I see this a lot.
What to expect? - anger - rebellion - possible violence - denial - overreaction - escape - crying - frustration - indignation - complete failure An intervention is like jumping into a fire with gasoline to put it out. Get the help of a professional if at all possible here, this is hard and can be dangerous.To prepare the best thing to do is lower expectations, this will likely only be the first step of many, your nephew is lucky to have family and friends here to suggest help to him.
Be prepared to do the intervention again... and again. I am a recovering addict and I can say from my experience and the observed experience of others that we almost n e v e r get it the first time. Another thing to keep at the forefront of the plan is the knowledge that your nephew is very very very sick.
He will not be operating in a clear head.. not from the booze in his system necessarily but from what the booze has done to his brain. He is gravely mentally ill and will be unpredictable in his reaction to this intervention.. your plan must include sensitivity to this while remaining 100% firm in your intentions... you want him to drop everything.. yes everything ...and get to a treatment program today.As this is the first intervention this will be less formal than the next one but you still should have a recovery plan set up for him to get into right away, you should be ready to cite every example that you have as a reflection for him to see himself as you the intervener do, try to do this when he is not drunk.. likely will not be possible but do your best, notify his doctor that this is your intention because if he is physically dependent on alcohol then he will probably need professional medical attention to safely detoxify from the booze, be ready to 100% follow through with the planned consequences for his refusal of treatment .. tough love will test your better angels here, and above all else you have to remain focused, calm, and collected.. he will 100% test all of you...and probably viciously.. either with words or physical attacks. Each intervention is a bit different so this is a good framework to begin with but you and the rest of the intervention will have to think, act, and react on your feet a bit.
Keep you intentions at the front and remember he is sick.. very sick and his mind will tell him he is not.. he will believe this.. and not you... be careful and good luck.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
