People have been mind controlled through the "education" system to learn not to Love. Most people don't even love themselves (because they don't know Who and What they Really are), hence the intense and ubiquitous pathology we currently see in the world.
You're exactly right. We need to learn to Love ourSelf again and that starts with Knowing the Self.
"Heed these words, You who wish to probe the depths of nature: If you do not find within yourself that which you seek, neither will you find it outside. In you is hidden the treasure of treasures. Know Thyself and you will know the Universe and the Gods."
Delphi Oracle
I completely agree. In the end there is no outside. Everything is projection of our inner state. If you want to have peace, be peaceful. Wars are just projections of our inner disharmony.
