Keeping the same original idea for special occasions

I must say that I really like the Israeli blue and white flag in times of war.  It makes a nice war flag as the banner is attached to a tank or vehicle and drawn across the desert of the middle east as we have to unfortunately advance the front against the enemies of Israel. 
By no means should we eliminate the blue and white Israeli flag. 
I am not suggesting that we make this change, but I just want to present the concept in hopes that if it is meant to be, someone else will run with the idea.  Perhaps this yellow, blue and white Israeli flag of the State of David will be a marker for stability in the region.  I think that personally  a yellow addition would look great with the background of green flags in the middle east.  Perhaps and I will go out on a limb here, if the arab nations see this new yellow and blue and white flag, they might not have the same anger and resentment in their minds that they have displayed towards the white and blue flag.  Truly this would be for a situation where there are two different flags and for different occasions. 
I just present this idea here and hope that perhaps it might have some use to the future.
