or earlier i spoke with joe metella in the sacramento, so she's a senior lecturer in security and development at kings college london. she told me more about the non persistent landlines that the us defense secretary was talking about i think what, what is meant is, are these non lines very kind of safe destruct or they have, are sure to sort of live span because the sort of a lose the battery charge, and from what i've read, you know, they could, they could be active be between sort of from 4 hours to maybe 2 weeks. so they're not on minds that, that are active for, for long, long periods of time. and therefore, they are a lot less dangerous. i mean, the question that arises in my respect is, in this respect, is, you know, to what extent companies to be considered deficient. because if they have these live span, then what you would expect is that the russians might wait until this live spanish is over. so i think we need to find out a bit more about the technicalities for our job. what is clearly said, if my minds are deployed, you know, they, they can help to lead me to a certain extent. al
