I think Aries would win. Aries are insensitive and fearless fighters while Leos do have a heart and can't be so cruel, which is basically a good thing.
Aries versus Leos.... hmmm this is a good one. Both are of fire element and tend to have bad tempers, Aries are headstrong and are able to tackle any challenge.( Depending on the Aries and depending on the challenge) These signs can be physical when tested, unfortunately just like a fire, if not tended it will surely burn out quick. In general Aries are the impulsive, ACT now, "let go and do this!" kind of people, but will surely burn out in no time.
Leos on the other hand have their pride to protect, since they are good with kids, they tend to be childish themselves. They will out do and try to trump you in every move, but you really have to push them to the limits or provoke them, rarely ever saw a leo become the instigator or start a fight, verbally or physically. Remember Leo's gemstone is the peridot (if born in the month of August) signifies protection.
If Aries going to start a fight with a Leo, you can bet your pretty shiny penny Leo will finish it, but that's if the lion has a interest to protect......if caught in a dazed you can surely agree with me that the Aries can catch a Leo by surpise and ram him/her a bit for a short time. Might be a bloody one, if physical. But Leo will come on top.
They're Kings/Queens!
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.
