The impact of wars aren't measured in their casualties, but in their sociological, political, and geopolitical consequences. The Arab Spring represents a major shift in the Middle East and the muslim world from dictatorships toward democracy while the rise of ISIS in Iraq and Syria and the Muslim Brotherhood in Egypt and Libya represent a threat to the democratic and populist movements that deposed the totalitarian states that have dominated the region since the Cold War.
This shift was precipitated by the War on Terror in Iraq and Afghanistan (especially Iraq, since it deposed the powerful dictator Saddam Hussein and destabilized a powerful Iraqi state), as well as the rise of the Internet and mass media. The ramifications of the sociopolitical shift in the Middle East and North Africa could have an effect on world politics for years to come, considering how much oil is in the Middle East and how reliant on oil the West is. Just look at the multinational intervention against ISIS, and the proxy war between NATO(mostly the US) and Russia in Syria, the proxy standoff between Russia and the US over Iran.
And the crisis in the Ukraine is of utmost importance because, although Ukraine is not a member of NATO, it had intentions to join NATO and has been shifting towards the West for years, which is something that Russia (especially Putin) views as a threat. Ukraine is just a test, to see what NATO and the US will do, and Georgia in 2008 was another test before that. Next in line for Russia's revanchist geopolitical tests is obviously the Baltic States, as indicated by their cyber assault on Estonia back in 2007. The only difference between Ukraine and the Baltic States is that the Baltic States are part of NATO. Putin can and will test the integrity of NATO by threatening the Baltic States. He will slowly escalate until NATO makes a stand or World War III breaks out. This is why I want these events to be on the Timeline.
