Rabbi Moshe Feinstein [ZTL ZYA] was accepted as the highest posek by BOTH the Chareidi Yeshivah World AND the Modern Orthodox.
So far as I know, he was the last Rabbi to hold that distinction.
This demonstrates how much the situation has deteriorated since his death in 1986 CE.
Additionally, it is dangerous to say:
�Bridging the Gap Between The Torah World and MO�,
because it could cause the Modern Orthodox to believe they are NOT part of �The Torah World�.
That is much more likely to push them farther away from Torah, than it is to draw them nearer.
Rabbi Moshe Feinstein [ZTL ZYA] once said that it is very important that EVERY JEW consider himself to be Orthodox, regardless of his level of mitzvah-observance.
