Will Czech withdrawal of US Radar Treaty scupper Lisbon?

The report from Prague is here, this is the relevant quote:

A: Is there a danger of "killing" the Lisbon Treaty? ODS congress recommended not to approve the Lisbon treaty before the radar base treaty is ratified.

(PM Topolanek): I think it is possible (the end of Lisbon treaty). But I would stress it is not entirely our responsibility. I will not instruct anyone how to vote and in which case. I have said that many times before.
