Paul Maillet is a retired colonel from the Canadian military and a full-time peace activist. Sam Lanfranco is a retired professor of economics and a member of the Internet Corporation for Assigned Names and Numbers (ICANN). We discuss the lessons and dilemmas for policymakers from the unexpected invasion of Ukraine. He fully expects the Ukrainians to prevail eventually because it would take a million soldiers to occupy a country of 44 million if they fail to cooperate. But in the meantime the destruction may be ghastly. We discuss nonviolent resistance strategies and the new way of fighting with economic measures. Sam Lanfranco joins us late but can report on discussions within the Internet governing bodies as to how. best to use the Internet during and after this conflict.

Ted Kesik is an engineer who teaches in the architecture faculty at U of Toronto, where he specializes in building materials and constructions that contribute to social resilience. With 300,000 immigrants coming to Canada each year, new dwellings must be built and the deteriorating infrastructure repaired and expanded. Urban drainage systems are inadequate, so we must either rebuild or use less water per person. As high-rise condos age, there will be more incentive to clad them with insulation and replace windows. Concrete and steel are going to be produced with zero net emissions, partly because of the competition with mass timber construction.

Ernest Thiessen's Ph.D. thesis was a search for an algorithm with which to solve conflicts by seeking to maximize the preferences of all parties to the dispute. He found one independently, not knowing that John Nash had already solved the problem (and Nash won a Nobel prize for it). Now he has a company that provides a software that can be used to find the optimum solution to a dispute that is locked in a stalemate. He can always improve on the status quo, though in real life hardly ever achieve 100 percent satisfaction.

Ellen Thomas held a vigil outside the White House for many years. She favors a bill that is brought to Congress every year but never voted on: to shift money from nuclear weapons to a useful economy. Canadian activists Robin Collins and Earl Turcotte disagree about the best policy for Ukraine. Turcotte thinks it is realistic for Ukraine's allies to defend it militarily, while Collins considers Biden right in holding back, since Putin might respond with nuclear weapons. Both agree that there is a confluence of two contradictory impulses because of Putin's threat: a desire to abolish nuclear weapons because their risks are made so apparent, but also a demonstration that they can be valuable deterrents. NATO will not go to war against Russia because he has nukes, and if Ukraine had kept theirs, he would not have attacked them. This is a terrible message but convincing.

Ben Rawlence is a British writer whose recent book, The Treeline, recounts his tour of the world around the Arctic circle, as he visited indigenous people living in all the northernmost countries. Their lives are being affected adversely by global warming, which is allowing trees to grow farther in the north than before. Different countries are forested with different predominant species, but the effects are generally negative, for the trees exacerbate the warming. Even caribou cannot survive in some of their former habitat. Rawlence has created a college in England that offers programs on topics relating to the environment and climate.

Harriet Friedmann is a sociologist, expert on the world food system. She worries that there are economic factors limiting the opportunity for farmers to adopt the newest and best methods of farming. Tom Newmark, who lives on his regenerative farm in Costa Rica, was formerly the head of a multinational food corporation, and he believes that all the major corporations are fully aware that the standard current agricultural methods are failing and must be replaced. He believes that these companies are taking the lead in promoting the changes that are inevitable because essential; there is no alternative.

Erin Hunt explains why the meeting is unable to proceed for the Convention on Certain Conventional Weapons: the Russians cannot arrive because the airspace is closed to Russian planes. Talk shifts to the causes of the Ukraine War and how to end it. David Burman sees it as caused largely by Western obliviousness to Russia's security concerns. This view is generally qualified by the notion that Putin would have attacked anyhow, and just uses NATO as an excuse. The talk gets more animated when there is a discussion about having Ukraine surrender but continue the conflict with nonviolent Civilian Based Defence.

Ole Hendrickson is a retired ecologist who also spends a lot of his attention on the risks of radioactivity. Here we talk about the renewed danger of Chernobyl and other Ukrainian reactors, which have been taken over by the Russian invaders. Then there is a conversation about Canada's forests -- especially the wonderful potential for urban forests and urban national parks. Hendrickson also explains the controversy over reprocessing waste fissile material.

Olivia Ward has been the Toronto Star's reporter from previous Russian wars - especially Chechnya. Erika Simpson is a political science professor specializing in NATO. Alex MacIsaac is the new director of world federalism in Canada. Real Lavergne was the head of Fair Vote Canada and Martin Klein is a professor emeritus of history, U of Toronto. We discuss the four-day-old war in Ukraine and its causes, including early enticement of Ukraine to believe they might be admitted to NATO, and even whether Putin is mentally unhinged. We consider various possibilities for a solution, including the Minsk Agreements, and the possibility of becoming a neutral state.

The February Town Hall found activists dispirited over Russia's attack on Ukraine, with only Abraham Weizfeld offering justifications for it. Some were concerned about the risk of radiation from Chernobyl and Ukraine's other nuclear power plants, which Russians now control, but possibly not properly. Finally we discuss the changes that need to be made to renovate the "world order" that had been fairly successful since World War II but which has not prevented this calamity.
