When Syria was trying to make a nuclear bomb about a decade ago, Israel used their airforce to bomb the weapon making facilities They also bombed Iraq too...I don't understand why the US did not do this years ago?
Its too late to do that now, as they are quite advanced...I know the US could crush North Korea but invading would be the worst idea ever....millions of South Koreans will die instantly so will thousands of American soldiers....much more catastrophic scenario than the Iraq Invasion of 2003.
I think this was all to pressure China they have don't jack shit with regards to North Korea
