Joseph,
As I understand the majority of the Torah leadership of Agudas Yisroel was against the formation of the Jewish State before 1948 and has accepted it as a Fait Accompli (an accomplished fact)afterward. Most likely the opinions of 4 of the 5 leaders you mentioned above were from before 1948.
Fait Accompli example: A couple gets married against our advise and have children. Afterwards we will pray for their happiness and success.
