> That's probably because the wars started by "the West" (US and allies) are significantly more than the wars started by Russia or the USSR. See: vietnam, Korea, Iraq, Afghanistan.
Korea was started by a USSR ally (North Korea invading South Korea), the UN Command (led by the US) was a defensive response.
Vietnam is...well, the whole post-WW2 situation in the region is complicated, but it's reasonable to view it as started by Western allies of the US, particularly France.
Iraq 1990- was started by Iraq.
Iraq 2003 was started by the US.
Afghanistan 1980 was started by the USSR
Afghanistan 2001 was started by the al-Qaeda, a force intimately connected to and defended by the Taliban and based in Taliban-held territory, attacking the US.
Your list of examples doesn't really make a strong case for your thesis.
