Hey, we're Americans, not some kind of progressive island nation with 10 million people. We're a huge moving ship of 300 million and it takes time to change things, chip + signature is a huge step in the right direction. Why? Most of the scams involving purchases with stolen credit cards involve "carding", or simply stealing the magnetic strip data and reusing it online and on duplicated cards.
The chip eliminates this as the chip can't be skimmed in practice. The big credit card folks (EMV) would love to have you typing a PIN as a second factor, but realistically the chip alone will dramatically reduce credit card fraud. It's really going to be important after Oct 1st for retailers to support chip cards (Many readers now ask you to insert the chip portion of the card in the reader after a magnetic swipe...

Things like Apple Pay and (soon?) Android pay help with this as well, as skimming a tokenized version of your card is nearly impossible and not reusable.
I recently (last week) had a Amex card compromised, the carders first tried a $1 transaction on a whatever site, it passed, then a few hours later they took the card to nordstrom and tried to buy $1000 worth of crap. The Amex app on my iPhone notified me of a "potentially fraudulent transaction" and gave me a yes/no to accept the transaction. I clicked No of course, which caused them to call me right away and cancel the card. The Amex card that was used for my Apple Pay (which I use frequently) was *not* affected (as it is a tokenized version of the card)
These carder folks use legitimate websites to "test" the card, I read about this case here:

For the record, I'm guessing my card was stolen at a gas station, which they are exempt from the new EMV laws until 2016 (according to the time article above)
