Can the VA take my Retired Military Dad's pay if my brother has Power of Attorney over my Dad?

Please forgive me if I'm not explaining this very well. I'm not versed in all of this. Okay. We are trying get my Dad higher than the 60% rating he is. That way when he goes to the VA to live, he would not pay so much out of pocket. My Dad has Dementia, yet he's at home and not so bad off that my brother and I can't take care of him. Plus, my brother is legally my Dad's Power of Attorney and has papers to prove it. Now the VA is saying that they are contemplating making him a ward of the state? Government? (I'm sorry, I'm a dufus ;] and they would have authority over his money. My Dad lives in his own home and I live with him to meet his physical needs and whatever. My brother takes care of his finances and medical appointments. We have no problems with it being a hardship taking care of my Dad. I was wondering if the Government took my Dad's money, they would only pay his bills and utilities. We take my Dad on trips to visit kinfolk, fishing, and whatever he wants to do. We want to give my Dad quality of life before he leaves us. I don't think the Government would give him enough money to do those things. (We spend our money too) And doesn't my brother's Power of Attorney override them? Help us please or at least point us in the right direction. Legal Counsel? I don't want the Government to take my Dad's money and give him an allowance that he can only buy sodas. Thank you so much and I'm sorry it's long. Thank you.
