It is pretty evident to me just based on the context of what O'Sensei's war and post war experience, how he was for peace in society. In case then love could have meant peace, or anti-fuedalism. That is peace on a global scale and not a mirco-scale such as mediation, or mental etc.
And the scholar I mention is a seasoned and well respected Aikidoka.
I hope that clears it up.
