In the last 25+ years, what has Russia ever done to us. Do have 3 specific cases?
“Russia is our friend”
Putin is NOT out friend
Done to us or our strategic national interests? The Russian takeover of the Crimea and invasion of East Ukraine is one specific ongoing case. They also shot down a civilian airliner.
Second. The construction of nuclear plants in Iran and providing them with anti-aircraft missiles is a threat to the region and our allies, including Israel.
Third. The support of Assad regime which harbors terrorist groups like Hezbollah and Hamas and tried to obtain nuclear weapons. Israel's preemptive strike took our Syria's nascent nuclear facility.
Fourth. In August 2008, American-Russian relations were strained, when Russia invaded Georgia. Russia claimed that it was a mission to protect Georgian separatist regions of South Ossetia and Abkhazia from Georgian bombing of civilian areas. The United States supported Georgia in the conflict, sending humanitarian and military aid to Georgia and assisting with the withdrawal of Georgian troops from Iraq.
Fifth. Relations between the United States and Russia worsened when in late July 2013 Russia granted political asylum to the former NSA contractor Edward Snowden, who was wanted by U.S. prosecutors for theft of government property and espionage. This further aggravated relations between the two countries and led to the cancellation of a previously planned one-on-one meeting between Barack Obama and Vladimir Putin that was scheduled for early September 2013 in Moscow, Russia
Sixth. The Russians have taken provocative actions violating US airspace and buzzing our aircraft and ships in international airspace and waters in many locations around the world. For example, a Russian fighter jet, flying at high speed, came within 10 feet of a U.S. Air Force reconnaissance aircraft in international airspace over the Black Sea in May of this year. List of incidents involving Russian military and Nato since March 2014
I could add many other cases of what Russia has done to us over the past 25 years. You have asked for three and I have provided six.
