Actually, the Democratic party has been in power during war years moreso than the Republicans.
The bulk of the 1960's when we were in Vietnam were years that the Dems (mainly Lyndon Johnson) were in office. The economy was in full gear during this time with the war on, though, the the stagnant 1970's economy was probably the result of policies of the 1960's. The 1970's economy was described to as ,"stagflation", a stagnant economy rife with inflation.
In the early 1950's the Korean War started with President Harry Truman (Democrat) in office.
In the 1040's, World War 2 had Franklin Roosevelt (Democrat) in office.
Can I characterize or surmise the Democrats were *war mongers* because the bulk of American involvement in wars were during Democratic administrations? Of course not!! Can I accuse FDR of intentionally provoking WW2 (Japan's attack on Pearl Harbor) to break the back of the depression? Absolutedly not.
These Presidents (especially Roosevelt & Truman) were simply dealing with the global situation as required.
Eisenhower presided over the bulk of the 1950s, the economy was strong and relatively peaceful (not including the Cold War).
The early 1980s, we painfully shed the 1970's inflation cycle in part by raising interest rates. Mortgage rates approached 20%. You really can't imagine that now, especially if you're young and came of age in the 1990's with rates at 8% and going down to todays rates.
Continental, from your profile age group, you've only experienced economic and stock market good times. But good times and recessions come and go in cycles, this is nothing new, though it may be to you.
9/11 was being organized long before Bush was sworn in. It's now Bush's responsibility to deal with it, as was FDR was responsibility to deal with WW2 and Truman with Korea.
You're only as good as your last departure.
