If this merger works out like how it does in business world. It'll be office politics bonanza like medieval kingdoms battling each other for upper hand.
Eventually organization with stronger culture will win out and dominate the new merged organization. Then business will be approached with same or extremely similar attitude and mindset of winner organization.
Except in this case, business would be Judo for USA...
I would love to see this work for the betterment of Judo in the US, but fully expect politics to ruin the chance of success.
