Sure. First I'm not Chomsky or Finkelstein but their POV is similar to mine on many issues. But to explain my POVand I hope I'm logicalI'm against all States. I'm not an anarchist, either; I see States as a necessary evil given the current state of human civilization. But they should not be glorified as a an end, but as a means to an end, the end being peace, security for ALL, democracy, people before profits, equality ect (progressive values). 

States should never be supported when they rest on the oppresssion of others. I oppose all conquest and imperialism, past and present. As far as states created by conquest, what is important is current oppression, i.e.  ending it,(esp. state-sponsored) that are in the bussiness of building based on conquest of others. This must be opposed equally in all cases, which a special responsiblity for those you can have the greatest effect in changing, stoping, i.e. if I live in the US, I have a special responsiblity to speak out against things this countries does (directly or indirectly as in the case of support for Israeli occupation).

As for the meaning of a national homeland, it could mean the country of origin and native land of a people who have a strong cultural connection and history within such a territory , a cultural geography. There are many ethnic groups who holds a long history and a deep cultural association different country or geographical regions, in particular where the national identity began. And, diffferent groups can live in peace side to side, with different language, cultures, co-existing with the same country, united under the common accepted cultural norms of democratic values. This does not negate a national homeland, only having it based on the oppression of others. Hence, I'm able to be for a national homeland for the Jewish people in the land of Israel while at the same time I'm anti-Zionist and advocate for a binational state.
