Must not have been too secret if the courts ruled on the appropriateness of warrantless wiretaps.
You didn't consider Iran-Contra "constitutionally questionable"? I'm sure there are other acts presidents have done in the interests of national security that were "secret."
Congress provides oversight primarily by passing laws. The president is supposed to follow the law. The courts determine whether the law is constitutional and whether the president is indeed following the law. I see no problem with that approach. It's working.
You're right, Iran/Contra was a secret war. Only the temperment of the Independent Investigator saved the Reagan administration from impeachment...considerin
g the country just went through an impeachment a decade earlier he did not want to put the country through that again. Some restraint hey? I wish the republicans would have put the country first instead embarking on the Clinton fiaso.
No the checks and balances did not work. Bush kept the US's torture policy and domestic spying secret from the Congress. Only after the programs were leaked did Bush consult with Congress and that was so that he could have retroactive immunity from obvious abuses of power.
How do you figure the Courts were in on FISA when Bush ignored getting warrants from the secret court? Your assertion makes no sense. The center of the case against Bush's domestic spying was that he ignored the secret court for getting a warrant and did not consult Congress on doing so, ie, he didn't ask for the law to be changed, he just ignored it and consequently committed a felony.
The Congress makes the law. The president enforces the law. The Judiciary interprets the law.
Congress provides oversight of the executive by, among other things, holding the purse strings of the country.
The Bush and Reagan abuses of power were done in
secret. Lincoln didn't abolish Habeus Corpus in
secret. Truman didn't order the US takeover of US steel plants in
secret.Surely you can see the difference.
