I believe we will see world peace too:)

Let's give peace a chance!
You would like to explain that you wish for world peace. Of course, you could also echo the message of John Lennon from the 70s from the famous anti-war song: 'Give Peace A Chance.'
If you desire something for the future you can start explaining this by using the structure: 'I hope that....'
I am 100% behind you here, wishing for world peace that is. But if you want to explain to someone that you wish world peace would actually be a thing then you can say one of these two sentences.
Do you wish for world peace?
All the time I wish for world peace.
Try one out, and see how you get on.
I hope this helps.
Have a great day.
Will
I want world peace.
