Winona LaDuke argues in her Oct. 10 commentary that despite the defeat suffered by opponents of the recent completion of Enbridge's Line 3 replacement pipeline, their strategies have been affirmed and the defeat offset by other victories ("Line 3 opponents can savor this defeat," Opinion Exchange).

She claims that "no one wants to finance more tar sands" because of low oil prices and the four-year delay in opening the pipeline. But what was $50-a-barrel oil then is over $80 a barrel now and rising daily, and the pipeline is now up and running at twice the capacity of the old one.

She's also pleased that Harvard University has begun divesting itself of fossil fuel holdings. But wouldn't it be better for concerned investors to hold onto their investments and use that leverage to lobby for positive change, which has shown some recent success? If Harvard's holdings are instead held by private equity firms, will they push as hard to phase out fossil fuels?

I've always wondered if the pipeline's opponents ever considered negotiating a replacement that ran along the old route but would have kept the flow at the half-capacity required by the aging original line. By holding out for total victory, they've ended up with a pipeline that has to follow a much longer route and will be pumping at twice the capacity for years to come.

Sometimes, moral victories might not be as valuable as they seem.

Annette Thompson Meeks, in her commentary "Side effects of voiding drug patents would be severe" (Opinion Exchange, Oct. 19), claims that the loss of patents on vaccines would result in the pharmaceutical industry and investors foregoing billions of dollars of research and development aimed at new and better medicines. Meeks neglects to mention that companies such as UnitedHealth Group have made high profits in the past year, and handed a $42 million package to its outgoing CEO.

Of course this indicates that despite the risks of new drug development, the industry has plenty of money to spend on direct-to-consumer advertising and nonresearch payments to physicians, journal editors and medical organizations.

A headline in the Oct. 15 Star Tribune reads, "UnitedHealth's profit soars past $4B." That's a quarterly profit. While performance like this may cheer investors and executives, it begs the question of how the insertion of insurance companies between patient and doctor serves the public interest. In the insurance world, every payment to a policyholder is classified as a loss. We know that the U.S. spends nearly twice as much as the average OECD country on health care, while having a comparably low life expectancy and high suicide rate. We have the highest chronic disease rate, the highest number of hospitalizations from preventable causes and the highest rate of avoidable deaths among peer nations, according to the Commonwealth Fund.

I advise the letter writers demanding gun control and pooh-poohing defensive gun use to access the Centers for Disease Control and Prevention website to note that the number of defensive gun uses each year are between 60,000 and 2.5 million ("Where are cases of self-defense?" Readers Write, Oct. 19). It is unfortunate that some die because of gun violence and could have been saved with draconian gun laws, but many thousands more would be lost without Second Amendment protections.

There was some flawed logic and purposeful mischaracterization of facts on display for two Oct. 19 letter writers over the gun/crime issue.

The second writer evidently does not approve of state Sen. Warren Limmer ("We need common-sense control — of criminals," Opinion Exchange, Oct. 15). The author purposely obfuscates the fact that anti-gun groups are not about limiting gun ownership. It is a clever attempt to recharacterize the virtue of their agenda. The writer also extolled the virtues of red-flag laws, which I support as a retired deputy sheriff. However they must be constructed in a constitutionally correct manner. Further, the existence of the law does not ensure it will prevent violence unless someone initiates the process to begin. Therein lies its limitations. Sen. Limmer's statement that "laws do not stop criminals" is correct. However, they do stop 99% of the public. That is why we have police officers, prosecuting attorneys and judges. But apparently that connection cannot be made by the writer.

Printing letters like these is a valuable service because it shows how people deny or twist reality to fit their own political agenda.

Colin Powell certainly deserves the recognition he has received since his passing ("A trailblazer, trusted adviser," front page, and "Colin Powell's extraordinary life," editorial, Oct. 19). His accomplishments as a military leader and secretary of state speak for themselves. All the romantic rhetoric about the "promise of America" aside, Powell is the enabler who promoted the lie about nonexistent weapons of mass destruction as justification for the disastrous Iraq invasion. The subsequent carnage perpetrated by George W. Bush, Dick Cheney and Powell's cohorts did nothing but waste money and lives in the service of a flawed ideology of which Gen. Powell was an enthusiastic proponent.

Of greater consequence is the loss of trust in American leadership. The lies and deception that have destroyed the credibility of our democratic institutions are a direct and proximate cause of our current political paralysis where individuals egged on by a former president stormed the U.S. Capitol. We can praise Powell's personal integrity and fortitude while, at the same time, maintaining a clear view of his tragic flaws. If democracy can survive in the desert of distrust Powell helped create, we may yet see the promise of America fulfilled.
