I like Krav Maga. It is an art of self defense 
It is used by Israel Defense Forces so it certainly has merit
Yes it is. I learnt a few lessons 
Krav Maga combines boxing, wrestling and street fighting.
That is true
But the philosophy emphasizes defensive and offensice moves all at the same time.  That sounds difficult
I like the defensive for self protection  
Yes, KravMaga is known for focusing on real world situations
The Israelis developed it into a weapon 
This was started in the 1930's by a Hungarian Israeli martial artist
