We can’t afford to fight Russia after spending more than a trillion on “war on terror”.
Especially when Russia is actually willing to define the enemy and kill them.
If we attack Russia right now, it will distract Russia from ISIS, enabling ISIS to continue to work to overthrow Assad; then Russia’s allies will galvanize against the United States and that will create even more chaos, likely an economic war and that is something we can’t sustain, we would collapse. That last thing we need is for Russia’s ally China to become a full open enemy and the Chinese could pull something that could collapse our already comatose economy.
