Isn't It Time to Change?

With Ukrainian President Volodymyr Zelenskyy in D.C. to beg the USA for yet more billions in weapons aid, it seems to me there's a big-ass, two-part question looming that shouldn't be ignored much longer: Please, isn't it about time to change tactics? 

Behind Door Number One is the future a ratcheted up aggressive strategy will buy; short of nukes, support Ukraine in attacking Russia however Zelenskyy's generals see fit. Ukrainian forces try to make the price on continuing the war too great for Russia to bear. 

Behind Door Number Two is the future that calling for a negotiated end to the fighting, ASAP, will buy. Tell Zelenskyy that to bring about an armistice, new mutually agreed upon boundary lines -- based on current conditions -- need to be established. Yes, for peace, be willing to give up on some land claims. 

One way or another, isn't it time for some end-game thinking?
