On the contrary, although the Chafetz Chaim obviously opposed secularism he supported the essence of Zionism in his time: buying land in EY and making aliya (Letters to his son Reb Ayeh Leb HaCohen pg. 43-44). The Gra, Chatam Sofer, Netziv, Avnei Nezer, Sefat Emmet and Ohr Sameach (who contributed to the JNF) also supported the essentials of Zionism.
It is a postive mitzva to establish a state as has already been proven here. This is a milchemet mitzva (obligatory war) as set forth explicitly by Ramban (Rambam apparently includes it in the mitzva of living here). The rest is up to succeeding generations.
