Why are Republicans dovish on Russia but hawkish on China?

[Unpoisoned Chalice]

Overall their argument is that China is more capable militarily and economically than Russia and thus is the greater competitor. This in and of itself makes sense but what does not is Hawley's insistence that it is somehow impossible to simultaneously aid the defenses of Ukraine and Taiwan. The general dynamic seems to be politically driven. The Trump-Russia controversy and first impeachment contributed to this as well as a reflexive opposition to anything perceived as being a fashionable liberal cause. China being governed by the Communist Party is also a factor.
