The placement of the malware that deep within the Russian grid had never previously been attempted, the Times reports, and is intended partly as a warning and also to put the US in a position to conduct cyber attacks should a significant conflict arise with Russia.
Pentagon and intelligence officials describe to the Times "broad hesitation" to tell Trump about the details of the operations against Russia. They tell the Times there was concern over how Trump would react, and the possibility that Trump might reverse the operations or discuss it with foreign officials.
"Do you believe that the Failing New York Times just did a story stating that the United States is substantially increasing Cyber Attacks on Russia. This is a virtual act of Treason by a once great paper so desperate for a story, any story, even if bad for our Country....." Trump said in one of the tweets.
The Times responded to Trump's tweet, pointing out its note in the story that they had spoken to national security officials who had no national security concernsabout their reporting.
In 2017, Trump shared highly classified information with the Russian foreign minister and Russian ambassador to the US in a White House meeting, The Washington Post first reported and CNN later confirmed.
Apparently, Bolton didn't want Trump to know anything about for fear he would tip Russia off or stop it altogether!
