perhaps the force field is not ready yet -

it does occur to me as I think about it a little bit further that the developments in the technology for a force field may not be sufficiently developed yet to take over the task of preventing everything unwanted at the southern border of the United States yet - so it just may be necessary to deploy a physical barrier usually referred to as a wall a fence or whatever in the mean time while we wait for the technology to catch up with the need since things cannot go on as they are - that is unacceptable - so as much as one may not want it - we can say that the cancer needs to be cut out or bombarded as long as another method of curing the cancer has not yet been fully discovered and begun to successfully implemented -
