100% correct. These wars are just wars on a little inconsequential planet in an inconsequential life. Billions have come and gone before us in similar ways. Allah has created a Universe with 200 Billion Galaxies, each one containing Hundreds of Billions of Stars, and our star alone (the Sun) is the size of 1.3 Million Earths, to begin with, we can never even start to understand Allah's creations and his plans, even if we got a life of a Billion years. In such a HUGE creation, people think anything happening on this tiny planet and tiny life is of any consequence at all ... and start questioning Allah's plans. Its sad.
They forget that as per Quran this life is an illusion after all. And they fail at this illusion when they start questioning Allah's will in regard to this life. That is why Allah asks people to look at heavens and Earth, so they would understand.
