Israel is a sovereign nation, and they can take care of themselves.
Unfortunately, if they go off, half-cocked and hit this facility, it is likely to have negative consequences, and the US is likely to be dragged into the conflict. This is bad for the United States.
I just wish that Israel could stand on its own, without us being dragged into the conflict.
Also, I think Israel is wrong for hitting this nuke facility if they decide to. From my research, things are not what they seem in regards to Iran and their nuke facility. There is a lot of propaganda in the media these days concerning Iran, and not all of it is true.
Do your own research, don't just believe me at my word. Try to read information from NON-US sources, that are not construed as pro-Israel/anti-Iran. Try unbiased news sources. The truth is somewhere in the middle.
Don't trust our media, they helped get us into Iraq and A'stan, and look what ClusterF's those were. I really love our troops, and I fear they're not being utilized correctly by our government and their handlers. I think they'll get us involved in another long draw out conflict that will cost us many American lives, and won't really help us gain anything.
